I hope somebody would stop him. Using nukes in a war is just too bonkers to contemplate. Sure they would be small, but the road to big starts with small.
Dropping the bomb will be a massive loss for the US as it’ll legitimatize nuclear warfare. Right out of the attack, the US ceases being the first firepower and becomes equal to the rest of the nuclear ones.
Next Russia takes Ukraine in a week and rich countries will buy nukes from North Korea and Pakistan.
Ever play Doom (2016)? It's about renewable energy.
Pesky little--very minor--side effect that it's extracted from Hell, and using it causes the denizens of Hell to spill over to our side. One would say they are "unleashed".
By raising the price of oil so much, our dear leader is trying his level best to accelerate the transition away from fossil fuels.
This is a terrible idea. Assuming nothing bad happens (other than the mass death, of course), there would be shocked pikachu faces from half of Americans and then some, not to mention those in other nations. If something bad happens (edit: other than the initial mass death, of course), the faces would instead range anywhere from panicked to vaporized.
He has considered it. He's a psychopathic fantasist. No one sane would have started this war.
But the consequences would be catastrophic. Not least that Russia would very likely nuke Ukraine to try to force a surrender. And France would have to decide whether to respond in kind.
Trump would not - of course - nuke Russia. Likely not even if Russia launched a first strike.
And it's unlikely Iran would surrender, because Iran has set itself up as a patchwork of semi-independent forces. The immediate response would be a mass missile strike on desalination plants and oil installations in Israel and the Arab states.
The absolute best outcome would be plumes of smoke all over the Middle East.
The worst outcome would be all of the existing minor nuclear nations - North Korea, India, Pakistan, Israel - deciding the safety was off, and why not?
This is the guy that ignored warnings that Iran would respond by closing the Strait of Hormuz. He was briefed on exactly this scenario and decided he knew better. That is to say he's been proved capable of making incredibly bad decisions, it's just a matter of who speaks to him directly before. One of these days it might be the wrong person.
