Huh, I figured that a president toying with WW3 would be the most concerning to world leader's and their SOCIETIES around the world.
Russia is a nuclear power (one of the biggest), and it's toying with Ukraine like it has been doing (I guess trying to show it's bravado on whooping them the old conventional way), is probably going to run out soon, otherwise if they lose big in that theater due to outside means.
If it turns nuclear on that battlefield, then the world will turn, and quickly reassess or begin to hate anyone who played along in the possibly knowing of the lost situation if nukes are applied... The world will begin to back off from anyone that had enabled that situation to escalate after they knew that the final command would come forth eventually if things escalate beyond the pale.
They will hate those that would have aided and abedded another catastrophe to take place in regards to nukes being unleashed in the world once again in a hot war.
They will figure that other options would have been better, but couldn't see the options due to all the crazy going on in the rhetoric that was spurring on and/or leading it all on instead of working tirelessly for peace.
Not sure where we are at in it all, but we can't ignore it or ignore our role in it.
Hope I'm wrong about such things, but who knows.
