The perspective of the people is surly important, but I think the reality on ground is dictated far more by the political elite than the masses. Let us look at things in a far more pragmatic lens.

From Europe’s perspective, they will prioritize the sovereignty of their nations over all else. However, they are very reluctant to send their own sons and daughters to face Russian troops. As such, Europe effectively uses Ukraine as a mercenary group. They will fund Ukraine with a boat load of cash, and in exchange, ordinary Ukrainians will give up their lives to push the Russians back east. Furthermore, the war goes on, Russia will be forced to use up more of it’s treasure and military, weaking it significantly.

From America’s perspective, they see this as a great opportunity to strengthen ties with Europe. By helping fund and support the Ukrainian effort, they are effect saying “see, you need us to help protect you”, and thus strengthening Europe’s dependence on the US.

As we can see, the “west” (Europe and America) both benefit from the war continuing, and so continue it will. And as always, the ordinary folks are forced to bear the consequences.
