Putin remains safe in the popularity stakes too, with iron control over Russian media, he portrays the macho man image popular with is the poor and powerless. Zelenskyy however would seem to be more at risk. If Trump cuts weapon deliveries (and there must be a lot of them!) he will be at risk from pro-Russian factions in the eastern countries of the EU.
It seems that all sides will have to concede territory. Eastern Ukraine has large numbers of Russian heritage and speaking population. Whether these people want a return to Russian sovereignty is debateable but could be a deciding factor – but who will be able to tell? A fair election is impossible in a war such as this. Repatriations are out of the question re:WW1 but it does not have to be a bi-polar issue? Power sharing – probably a fantasy as both sides have a different concept of democracy (or at least we do? – and we fucked up on a bi-polar vote – BREXIT).
Israel says it has killed a Hezbollah leader in a blitz on Beirut. It should be careful what it wishes for. It may feel that Trump is a sympathetic ally, but with a majority on Congress he may take USA first to a new level. Muslims did not turn out for Harris so he may be mindful of their support? Whatever the legalities of their attack on Gaza, I believe their attacks on Lebanon are another matter. Iran will be courting allies, although the schism between Shia and Sunni, Iran/Iraq and Saudi Arabia may be pivotal, although I am totally ignorant here!
