It's pretty straightforward, you are supporting for the call for the US to arm Ukraine. They don't do so for nothing. You are encouraging them to be the world police, actively supporting them doing so.
Grossly naive in many, many, ways. There wasn't a 'world police' before the collapse of the USSR, that's what Yalta was all about. Earlier empires were generally interested in specific territories, not in starting world wars. That didn't change until the twentieth century, where there were a couple of attempts to do so. And small countries weren't 'much much worse off' during the cold war, they had the ability to play the big blocs against each other, to extract a slightly better deal. It didn't always work, obviously, but quite a few places (Africa & S America especially) took advantage to break away from their colonialist powers.
Single superpowers only look any better if you are part of their bloc, which is why so many countries haven't voted in favour of those UN motions.
