So in that context where you say the USA supplied weapons to Israel & China/Russia/Iran to Palestine (Hamas) - now it’s about the same move if Iran/China/Russia attacked USA directly (USA is just doing it first)? Just a (more or less)proxy war taken one country-step in the Iran’s direction?

I don’t think that’s fair tho since I don’t think China has much plans on ever invading USA. I’m not even sure USA has such plans for China (or Russia). Both empires are just seeking to broaden their influence, the tactics vary a bit, but it’s about the same deck of cards.
