I dont think you understand what Iran has been targeting-
they have been gutting american property in the region
they have taken out data centers owned by amazon and microsoft - caused massive data losses - oil refineries - lng fields
Citi bank and other multinationals have lost billions in property and assets so far - they are holding trillions of dollars hostage in the persian gulf
and causing financial losses that increase exponentially by the hour
the guys that own the US are taking these losses - getting their $$$ fucked with
if US could stop the missiles, they would have done it the minute the strait was closed or after a tanker and a cargo ship got hit by missiles
They have redundancy to their operations, and I suspect the operation in Venezuela was there to mitigate these losses. But let's look at the situation in full. Nobody in the U.S. is without water, heat, light, internet, or gas. So at the end of the day, as far as the U.S. as a whole, it's a minor inconvenience, but to them they risk being blown up, losing water, power, energy, money, jobs, oil, and the longer it last the more it is going to cost to rebuild.
Mater of fact, I read that their drone factory has been blown up, and for them to replace that it might take a decade. As long as the war is fought in your border, you are at a big disadvantage, especially if you lack the capabilities of attacking their soil, and especially if the nation has more money and resources. Because nothing is worse than having your airports destroyed, water destroyed, power destroyed, and an embargo preventing other nations from helping. Because once the economy is destroyed, there is nothing left.
BTW, if the U.S. were really losing the war, they would simply destroy their oil plants, making sure their economy is permanently destroyed. Without the capabilities to do it back to the U.S., they are at a steep disadvantage.
