Yes. Cooperation among the remaining liberal democracies is important. We are all in the US/Russia/China crosshairs.

Taiwan, Japan and South Korea do care. They are very much afraid that if Russia succeeds, then China would follow suit.

South Korea understands the Ukrainian Territory of Donbass is a training ground for Kim’s army. And Japan has disputed land to protect from China and Russia.
