I hope Europe countries and Russia are smart enough not to intervene in this conflict.
Let's hope that they won't but it seems that Trump has already responded and he won't reply back to the said attack. I've read that it can be a diversion attack for Trump's impeachment and making him like a hero for declaring peace since elections is near on US.
That's base from socmed comments.
It really does look very altruistic. I hope Trump did it for world peace, not personal interests
