I was suggesting a solution to the problem for the US, not the world. Current US policy doesn't seem to give a damn about anyone else anyway.
Of course the threat is greatest for those closest who don't have equal or greater resources.
There is nothing good about nukes regardless of who drops the first one or why. Nothing.
Our Dear Leader seems awfully eager to push that button, and I don't see taunting KJU, threatening to destroy his entire country, or threatening to renege on a nuclear agreement with another country as a road to a peaceful solution.
People who are "quaking in their boots" because KJU may be able to drop a bomb on the US mainland or Guam probably don't want to become the incinerated targets of a successful attempt. Or suffer from fallout years later.
So are you implying by your choice of words that that makes them cowards? How silly of them to be concerned with a little thing like that, when they could be busy worrying about immigrants or walls or something.
