actually i think russians have more of a reason to invade since its across the border rather than the other side of the world and ukraine wants to join the organisation NATO which was set up to oppose russia and which they were promised to not be expanding
lets just say these ingredients happened in australia, if in the 1950's china had an anti australian organisation called SPTO, the south pacific treaty organisation set up because china, vietnam, indonesia and north korea wants to make sure australia doesn't expand, if australia attacks any of these countries then they would all go to war against australia
then aboriginals in NT want their own country, australia gives it to them in a referendum but then the new aboriginal country joins SPTO and soon chinese, vietnamese, north koreans and indonesians are on former australian soil
i guarantee if that happened then you would feel uneasy and want to know why there seems to be a SPTO expanding blob still trying to fuck with australia
