nuclear strike or to ban it altogether and impose an NFU policy. The Senate Foreign Relations Committee chaired by Bob Corker held its first meeting on the President's authority to use nuclear weapons in 41 years. Since 2017, Ted Lieu, Ed Markey, Elizabeth Warren, and Adam Smith all introduced bills to limit the President's ability to order a pre-emptive nuclear strike. Calls to limit the President of the United States' ability to unilaterally launch a pre-emptive nuclear strike increased after the January 6 United States Capitol attack. During the 2020 United States presidential election the eventual victor Joe Biden expressed support for a "sole purpose" declaration confirming that the only use of U.S. nuclear weapons would be as a deterrent, although this is distinct from a "no first use" declaration identifying that the United States would not unilaterally use them. Pakistan Pakistan's Foreign Minister Shamshad Ahmad warned that if Pakistan is ever invaded or attacked, it will use "any weapon in its arsenal" to defend itself.

Pakistan's National Security Advisor Sartaj Aziz defended the policy of first use. Aziz stated that Pakistan's first use doctrine is entirely deterrent in nature. He explained that it was effective after the 2001 Indian Parliament attack and argued that if Pakistan had a no first use policy, there would have been a major war between the two countries. North Korea North Korea's stated policy position is that nuclear weapons "will never be abused or used as a means for preemptive strike", but if there is an "attempt to have recourse to military force against us" North Korea may use their "most powerful offensive strength in advance to punish them". Israel Although Israel does not officially confirm or deny having nuclear weapons, the country is widely believed to be in possession of them. Its continued ambiguous stance puts it in a difficult position since to issue a statement pledging
