I generally agree with your assertions. Day by day less and less voices speaking up in favor. At least prior admins feigned an attempt to sway public before taking action. Admin is breaking records in losing public trust.
Assuming a conflict with Iran was inevitable - Do you think future state US would be in a better position to combat them than now? Also - as it's early in the conflict. Would a US win (regime change to western alignment) better position US interests against the real foes China/Russia?
The strategy of being unprepared for the Iranian response of targeting and disrupting trade is absolutely a clown show. Western Nations had plenty of time and data to build a contingency after recent main blockages and COVID restrictions. On top of the mountain of alleged top intelligence apparatus.
i personally dont see how a new western friendly regime (if we could even pull that off) is a net positive for the USA.
china got very little of it's oil from Iran, but some. so that hurts a bit, but only marginal.
China's greatest interest in Iran is weapon's supply that they can collect data from when they're sparring with Israel or the Saudis, both of which are supplied with US tech. so it was just a good way for them to real world war game gainst US weapons and interceptors. but while they cant do that long term, we're giving them MOUNTAINS of short term data. they now know that it takes 5 interceptors to take down a single missile, they will know our stock pile, they'll know our restock capabilities, they'll know how we coordinate the systems, where we take them from if we have a target we want to truly protect, etc. We're foreshadowing a future conflict and they've given us almost no data in return. soon we'll likely see drones vs drones if the conflict protracts, like in Ukraine, and maybe there we can get some real data for our own interests.
but overall imo its much better for china than the usa. its bad for iran, looks bad for israel, is really bad for other allies in the region, and the other fronts of the Israeli war are getting destroyed while eyes are on Tehran.
