It's a war that Ukraine is fighting for all western democracies. If Ukraine loses this war, as Jens Stoltenberg said, eventually that war will bleed out to Europe and beyond. We know that from Putin's statements. You've all read his manifestos, in which he foresees a reconstitution not just of the former Soviet Union, but of the Russian empire.
We know that the support of Ukraine's neighbours is particularly strong, because they know that all that stands between them and Putin is the Ukrainians.
