putin is a trigger happy bald man with a fuck ton of nukes pointed right at us. Would you rather have trump piss him off and get us all blown off the planet?
Why have you always have to start at -1 with you folks around here?
With nuclear attacks, depending on the size and, not necessarily, but also - retaliation, you are dealing with 'mutual ensured destruction' many times over. The dust of a couple of those explosions alone would gather in the atmosphere, producing something referred to as nuclear winter. Temperatures fall, crops die, more people die where you dont want them to, trade systems break down.
The 'crazy ivan' story for all intents and purposes always was a lie. Missile shields were a lie (thats generally offensive capability with shield printed on), and the only partner currently actively playing the nuclear armsrace are the US (moving out of disarmament treaties, increasing capability).
None of this has to do mostly or exclusively with what honcho is in office.
But if your only idea of politics is love given to a leader person, and then trying to interpret, what that person and another person would do with 'most powerful toy' when fired, because thats really all you are capable of thinking about... Thats more 'you' than the real world.
The only nation currently wanting to work on smaller, mobile, nukes, to use for strategic warfare are the US (they have the better technology they want to make that an actionable advantage). Allegedly.
Crazy Ivan nuking the world didnt feature in anyones current deliberations for about sixty years. Gbatempers to the rescue.
