The correct time to stop Putin's war of aggression was the day he sent troops over the border. He should have been met with ferocious force from the entire western world. But he observed the weakness in the West for decades and knew he could get away with it. Obama's failed "red line" was the end of any nation on earth taking the western world seriously. The end of western liberalism is nigh.
Clever reframing putting all the blame on Ukraine and the western world. You conveniently "forgot" to mention that Russia is the sole aggressor in this story. And no, Ukraine would have fallen a while ago already if not for western aid, so it wasn't at all for nothing. And then it would have been Poland's turn.
> Hundreds of thousands of Ukrainians would be alive now if not for this dispute
I mean, we (the west) could have saved ourselves a lot of money by putting it to Russia that if they crossed the border then we'd defend the airspace. Essentially, being half assed about it is going to cost more money and lives. The Ukrainians were going to defend themselves whatever we did.
I don't think Europe has a choice but to be involved.
> We have lots of problems of our own
I don't really understand that. You don't get to turn away from new problems and global problems because you have some economic issues of your own. Indeed, it's all the more likely to be why you get dragged in.
> The West has sent hundreds of billions of dollars worth of aid to Ukraine
We can afford it. The US is probably well ahead due to the sale of new weapons as well.
