You are too naive. Do you really think the US hopes the Russia-Ukraine situation gets heated? You are just being pretentious without knowing your place. In this war, it's Ukraine and Europe that suffer, everyone else, including us, is not affected. Why should a profitable deal be called off just because you say so? All three parties are willing to fight; do you think it's that easy to just stop? And this time with Iran, the US has to fight but can't really engage. It has to give Israel face while not pushing Iran too hard. Iran understands this; it's all just a performance. It needs to show initiative while letting the outside world know it’s okay. This is all for Israel's benefit. Iran wants international aid but doesn't want to act as a pawn, so its reputation is not good.
