Ukraine would probably not exist, and if it did, there would be a Putin Puppet heading its goobermint. Zelenskyy would be dead or in jail, along with Hunter Biden.
Likewise, NATO would probably not exist, at least in any recognizable form.
Europe would likely have caved immediately, and let Pootey have Ukraine, hoping he wouldn't go after Lithuania or Poland next - which he would if his armies were still intact after seizing Ukraine, which they would be if Trump was President.
Ironically, things would be a lot more peaceful; the genocide that is taking place in Ukraine would still be happening, but quietly, and absent the bombs, missiles and Property Damage, which would be ultra fine with Republitards who are mainly concerned with the latter.
