This responsibility, authority and accountability must be instilled into a single person. In our case, this is the President. This is a very important decision and a sobering duty. The sequence of events that would require nuclear strike happen rapidly. It is unlikely that Congress or any other body would be able to vote yes or no before our nation is destroyed. This is why the national command authority under the authorization of the President can launch nuclear weapons to save our nation. As more nations bring nuclear weapons online, we will have to even more lethal nuclear and conventional weapons delivery program. Alternatively, we could take actions to punish nations that are in the nuclear hunt before they pose a threat (Iran 🇮🇷). We can also wait for your city to smolder and then take action. What different world it would be if Hitler met an untimely end in 1937.
