Are nuclear weapons always ready or does it take time to activate them? What is the process if a country decides to launch nuclear weapon?
In the recent India-Pakistan war-like situation, the topic of nuclear weapon was again revived. The issue of radiation leak from Kerana Hills during the India-Pakistan war is also being discussed a lot on social media at a time when both are nuclear powers.
The process of activating a nuclear weapon involves several steps include various steps: Decision making, Command-and-control, Weapons preparation and finally launch.
The time to activate nuclear weapons depends on the military preparedness and technical infrastructure of the country.
Below is an estimate of the time to major nuclear countries:
United States of America: The United States of America has the world's most advanced nuclear programme. The US has land, sea (submarines), and air (bombers) based weapons that are always deployed which can be launched within a time frame of 10-15 minutes.
Russia: Russia's nuclear system is so highly advanced that it has automated systems such as 'Dead Hand' (Perimeter), to ensure a counter-attack. Russia's ICBMs, such as the Sarmat missile, can launch in a few minutes. Submarine and mobile launchers may take a little longer, but Russia's strategy is focused on quick response. It's estimated launch time is 3-4 minutes.
China: Beijing's nuclear strategy is based on 'no first use' and hence its weapons are not always in deployed position. Its activation and refueling missiles can take time. China which has expanded its nuclear capability in recent years can now launch new hypersonic missiles rapidly. China has around 350-400 weapons, of which only a few are deployed. Its launch time varies from 15-30 minutes.
India: India's nuclear policy is based on 'no first use' and 'credible minimum deterrence'. India's weapons are not stored in a deployed state. India has about 172 nuclear weapons, mostly land and sea-based. India will need a minimum of 30 minutes to launch.
Pakistan: Pakistan's nuclear strategy is focused on India. It has the capability to respond quickly. However, its weapons are not kept in deployed state. Pakistan has around 170 weapons, mainly ground-based.

After Israel-Iran war, another major conflict simmering in THIS volatile region; not India-Pakistan, China-Taiwan, the conflict is between...
File/Representational US-North Korea tensions The recent Israel-Iran war brought the world to the brink of World War 3, especially after the United States used B-2 stealth bombers to drop 13,000 pound bunker busting GBU-57 bombs on Iranian nuclear sites of Isfahan, Fordow, and Natanz. The conflict ended after 12 days the US mediated a ceasefire, which came into effect on Tuesday. North Korea-US tensions and threat of World War 3 There are other major conflicts raging across the world, including the Russia-Ukraine war, and the forever tensions between India and Pakistan, which present a real threat of spilling over into a global war. But, one volatile conflict which has been simmering for decades but often overlooked are the tensions between North Korea and the United States. After its recent attack on Iran, many geopolitical experts believe that US might be considering a similar operation against North Korea, which is a strong ally of its main rivals, China, Russia, and Iran. However, there is a major catch, North Korea, unlike Iran, is a nuclear-armed state with an estimated stockpile of at least 40 to 50 nuclear warheads, and nuclear-capable ICBMs with enough range to strike the US' West Coast. North Korean dictator Kim Jong Un realized that the only way to protect his regime from being toppled by a super power like the US, was to develop nuclear weapons, which he did, in addition to Intercontinental Ballistic Missiles (ICBMs) reportedly capable of reaching the US. Putin, Kim Jong Un may build stronger ties Experts believe that North Korea and Russia may build stronger strategic ties after the US attack on Iran, considering that Pyongyang has already sent arms and North Korean soldiers to fight for Moscow in the Russia-Ukraine war, and in exchange, received advanced military technology and oil from Russia. This strategic military and economic partnership between Russian President Vladimir Putin and North Korea's Kim Jong Un is expected to grow rapidly in the coming months in wake of how the US brazenly attacked Iran without any provocation on the pretext of developing nuclear weapons, a claim refuted by UN nuclear watchdog IAEA. Russia ties with North Korea are not limited to trade, but has transformed into a strategic military partnership that includes joint development of weapons, military exercises and technology transfer. Can North Korea-US tensions trigger a global nuclear war? Its highly-difficult for the US to attack North Korea in the same way it did Iran because unlike the Islamic Republic, Pyongyang is believed to have at least 40 to 50 nuclear weapons, and ultra long-range ICBMS to carry them all the way to the US, experts say, adding that it also a strong strategic partner like Russia. However, if the unthinkable happens and the US, particularly under Trump, launches an attack on a nuclear-armed North Korea, it will likely be met with a nuclear response from Pyongyang as Kim Jong Un has often threatened. This would trigger a catastrophic nuclear war, which might spill over in to World War 3, as every major nation gets involved and fires its nuclear weapons at their adversaries, threatening an extinction-level even never before seen on the planet.

Not Iran, The Real Threat Is Pakistan… Tensions Rise After US Report, How India's Warning Is Proving True
New Delhi: The maps in Washington have shifted focus. The chatter inside intelligence rooms is not about Tehran anymore. It is Rawalpindi. A fresh report from U.S. intelligence agencies has triggered serious alarm. Hidden under radar, Pakistan is reportedly building an intercontinental ballistic missile. It is said to be nuke-tipped that could reach mainland America. Until now, Iran had held the spotlight. But this new revelation has brought Pakistan's nuclear ambitions straight into global crosshairs. For India, it is vindication. For the United States, a potential crisis. For the region, a ticking clock. A report quoting U.S. sources claims that Pakistan's new missile has crossed theory stage. It is being developed quietly – away from public eyes. It is capable of traveling over 5,500 kilometers. That is ICBM territory. A range wide enough to strike far beyond Delhi. All the way to Washington. The report was published in Foreign Affairs – an American magazine. It says the missile project picked up speed after India's Operation Sindoor rattled Pakistan's military brass. With Chinese help, Pakistan is now said to be acquiring the components and know-how needed to leapfrog its existing arsenal. What This Means for America Washington is watching closely. Senior officials say that if Pakistan achieves the ICBM capability, it will be reclassified as a nuclear threat like North Korea, China and Russia. There will be no middle ground. The United States has already imposed sanctions. Last year, it froze assets and blocked trade with Pakistan's National Development Complex and its key missile contractors. That was not random. It came after evidence emerged of Islamabad sourcing sensitive tech from foreign markets. For years, Pakistan insisted its nuclear weapons were for deterrence against India. Nothing more. No ICBMs. No aggression. Just defense. But this new intelligence contradicts that script. With Shahin-III already reaching over 2,700 km, experts believe Pakistan is preparing to extend its reach far beyond South Asia. And there is a motive. If Pakistan owns a missile that can hit the United States, it will change the rules. It will act as a shield. It will limit U.S. involvement in any future India-Pakistan conflict. That is the strategy. Quietly but clearly. Why India Is Saying 'We Told You So' New Delhi has long raised concerns. That Pakistan cannot be trusted with nuclear weapons. That its command chain is fragile. That terror groups work hand in glove with rogue military elements. After recent air strikes inside Pakistan, India also neutralised nine terror camps and targeted 11 airbases. Pakistan reportedly fired a Fateh-II hypersonic missile. India shot it down. Defence Minister Rajnath Singh and other top Indian leaders have called on the International Atomic Energy Agency (IAEA) to monitor Pakistan's nuclear stockpiles. The concern is not hypothetical. It is urgent. One weapon in the wrong hands could mean catastrophe. While the world debated strikes on Iran, Pakistan was quietly reshaping its arsenal. The fear is not merely the missile. It is what surrounds it – terror cells, sleeper agents and political instability. If these missiles fall into the wrong hands, no country is out of reach. No continent immune. According to global estimates, Pakistan currently has around 170 nuclear warheads. It is not a signatory to the Nuclear Non-Proliferation Treaty. It also has a history of proliferation. That is what makes the new report even more chilling. The ICBM threat from Pakistan is no longer whispers. It is a documented risk. A weapon in the making. America now faces a choice. Ignore and risk a future crisis. Or act. India, meanwhile, continues to say the same thing - Pakistan's nukes are not only a South Asia's problem. It could soon become the world's.

After treating friend Asim Munir to a sumptuous lunch, Trump now warns Pakistan over missiles that can strike US
Why is the US worried about Pakistan's nuclear missile program? Live Events How close is Pakistan to developing an ICBM? Is China playing its long game to make Pakistan another proxy against the US? Trump's message to Pakistan: Lunch one day, warnings the next What is the broader context behind this move? Has Pakistan signed any nuclear control treaties? A global nuclear realignment may be unfolding FAQs: (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel In a development that's raising serious concerns in Washington, Pakistan is reportedly working on a nuclear-capable intercontinental ballistic missile (ICBM) that could reach the continental United States, according to a detailed Foreign Affairs report citing US intelligence story has caught international attention, not just because of Pakistan's long-standing nuclear program, but because such a capability would mark a dramatic shift in how the United States sees Islamabad—from a key regional partner to a potential nuclear report states that US intelligence agencies believe Pakistan is not only expanding its nuclear arsenal but is also developing ICBMs with the potential to hit targets across the Atlantic.'If Pakistan acquires an ICBM, Washington will have no choice but to treat the country as a nuclear adversary,' US officials told Foreign Affairs. 'No other country with ICBMs that can target the United States is considered a friend.'While Pakistan continues to insist that its nuclear program is designed solely to deter India, US agencies are not buying that narrative anymore. Instead, they believe Pakistan's missile development may be aimed at deterring US involvement in any future India-Pakistan conflict or a preemptive strike against its exact status of Pakistan's ICBM development is classified, but intelligence officials say the program is gaining momentum, with signs that Islamabad is sourcing critical technology and materials from China—a long-time push for a long-range missile capability reportedly intensified after Operation Sindoor, a covert operation that rattled Pakistan's military establishment, though the report didn't disclose specific details about that present, Pakistan is estimated to possess about 165 nuclear warheads, according to global defense analysts. Most of its current missile systems are medium-range, designed to counter threats from India. But the development of an intercontinental missile would represent a significant strategic is the question now dominating discussions inside US strategic Foreign Affairs report suggests that Beijing's involvement in Pakistan's missile program is deeper than previously thought. Intelligence sources point to covert transfers of missile materials, nuclear assistance, and joint development and Pakistan have long maintained close military ties, often described as 'higher than the Himalayas' by both governments. But this new cooperation—if tied to ICBM development—may signal a strategic shift by China to position Pakistan as a nuclear-armed proxy capable of putting pressure on the US from the West, while China and Russia ramp up pressure from the East and China expanding its own nuclear arsenal and Russia pulling out of arms control treaties, Pakistan's ICBM program could be part of a wider global strategy—one where the US faces nuclear threats on multiple fronts.'If Pakistan joins the club of countries that can strike the US homeland, the strategic landscape will shift significantly—and not in Washington's favor,' one senior US defense official was quoted as saying in the this rising tension follows a private lunch between Donald Trump and Pakistan's Army Chief, General Asim Munir, according to sources familiar with recent events. While the gesture seemed warm at the time, the tone has shifted is now said to be alarmed by the intelligence shared with him and has reportedly warned that the United States will not tolerate any attempt by Pakistan to become a long-range nuclear new revelations come at a time when the global nuclear order is under increasing strain. The report notes that as Russia walks away from arms control agreements and China rapidly expands its nuclear stockpile, the United States now faces a multi-front nuclear challenge—from two great powers and several regional threats, including North Korea, Iran, and now possibly Pakistan.'Mounting nuclear dangers now lurk in every region of vital interest to the United States,' the report nuclear journey began in the early 1970s, shortly after India's first nuclear test in 1974. In response, Islamabad accelerated its own efforts, culminating in six nuclear tests in May 1998, which formally made it the seventh nuclear power in the then, the country has developed a range of nuclear delivery systems, including ballistic missiles, cruise missiles, and tactical nukes designed for use on the Pakistan is not a signatory to either the Nuclear Non-Proliferation Treaty (NPT) or the Comprehensive Nuclear-Test-Ban Treaty (CTBT).
