I have no fucking idea.
I am waiting for them to start picking a fight with Turkey next.
Israel deciding to side with Ukraine would be interesting. But not as interesting as Turkey.
Turkey clearly isn't terribly happy (it eventually closed its airspace to Russia last week i think) but is still benefitting from the war at this point.
When Israel and Turkey stop benefitting, then you have to ask what does happen? .
They are key players in brokering peace atm, but since Russia doesn't look likely to do this, whats the point in that role?
Russia making a formal declaration of war has legal ramifications in theory. I believe that under UN rules all countries are supposed to stop trade with a country who declares war (Hello European states who import Russian fuel). Ukraine does not have the same problem, as its under attack and has the right to defend. It does not have to formally declare war back.
Where this politically might go with Israel and Turkey is interesting because as peace brokers, they will be pissed at a move to formally declare war and expand the war, especially if Russia is actively goading one of them.
