> Trump made the decision not to attack Iran and start WWIII after Iran downed a US drone
> He hasn't started any new conflicts
He has started a (completely unnecessary, in the opinion of almost everybody) conflict with Iran. The violation of the treaty and the sanctions are an act of economic war- which is much cheaper and less bloody than a military attack, but almost equally devastating for the victim. Trump is very happy with choking a whole country and he wants it to die in silence, without making too much fuss. Should he get a Nobel peace prize for that? I don't think so.
Not to mention the fact that Iran isn't happy at all at the idea of being silently choked so it'll keep staging provocations until either it can get a relief from sanctions or Trump is dragged into a war of his own making.
