What to expect from this US Iran war. When will President Vance replace Trump?

Let's call it what it is. The US war on Iran. Israel is just a proxy like Ukraine. 6/22/2025. Trump seems crazy to me to twist his campaign promises. I think the only regime change will be his. Trump will be removed by the midterm elections is my guess. The US hasn't won a war since WW2 so predictably things will not go well. If things dont go well its over for Trump in my opinion. As long as Iran keeps its head and doesn't attack the US, the war will end as a decided loss for the US or draw if history serves as a guide. China and Russia will keep Iran's head above water until Israel becomes like Ukraine. Seems obvious. This is just a gamble for the US. Desperate to halt Chinas dominance but a day late by my estimation. Who is the most powerful president in the world? Vance I would say....Trump just hasn't been replaced yet. BTW, the US failed at destroying Iran's nuclear capability even though the US says it was "obliterated". This glaring contradiction presented by the IAEA. I am liking Pence and possibly Vance better every day.
