Subject: Re: Trump unites Europe

Initiating a war based upon what another country might do in the future.

You really want to justify that as a casus belli?

Bush #43, and his NeoCon posse instituted the concept of "preemptive war". So, if the POTUS decides he wants to invade a country, and makes up an excuse, it's legal to start a war.

What would happen if Iran launched a nuke at NATO, or Israel, or the US? The UK, France, US, and Israel would nuke them back and turn Tehran into a big chunk of glass. Unless the Mullahs are more deranged that Trump the Magnificent, they would not start that war. MAD has kept the peace between the US, Russia, China, and North Korea, for decades. The only "national leader" I ever heard insane enough to insist that a nuclear war was "winnable", was Saint Reagan.
