Ukraine

Problem is that the only two other options is to either turn a blind eye on what looked like the start of a genocide, or having two nuclear power at open war.

Abandon Ukraine means it put its own wellfare above human rights, in which case Putin would be right to despise the West.

Go at war with Russia would put humanity on risk of annihilation as both side has enough nuclear weapons to wipe it out. Multiple times.

Having the Ukrainian choose their destiny by defending their land, while not ideal, is the only option that the West have to stay true to its ideals. The West populations are not blind to their sacrifices, and as long as they are willing to fight for their rightful territory, so are the West to provide the means to do so.
