I don’t think we are getting sucked in as much as we didn’t have a choice. Iran having nuclear weapons is not acceptable in any scenario, it is different than NK, Pakistan or Turkey developing nukes. Not only would they still hold at risk the Strait of Hormuz, they would still command some of the largest oil reserves and now a military capability that effectively holds at bay or at risk the world. They would have the means to if not push us out of the ME effectively, severely limit our options, if they developed a nuclear weapons capability. They are completely capable of nuclear terror, feigning innocence or ignorance if a weapon was used. It is completely conceivable they would strike us, Israel or Europe first with a nuclear weapon in an unattributable manner. Russia and China may be enjoying seeing the USA get into a fight with Iran and I wouldn’t intervene if I were them but we are not them. We occupy a totally different role in this drama, they can and will do things that we won’t because they, the mafia regime running Russia or the cult of personality running China, are the bad guys for lack of a better term. These are countries that might poison you with radioactive materials if the leader doesn’t like you or assign you to be worked to death and steal your organs if they want to. We are not perfect and neither are our leaders but by any measure we are more good than bad. I don’t like the fact that we secure a world that a lot of preening, hypocritical assholes free ride on and enjoy the benefits of while not doing shit but it is preferable to a world where China controls micro chips, Iran controls or threatens half of the worlds oil supply and Russia has retaken Eastern Europe. They will use that leverage to push us out, choke our economy and weaken us in ways we are not really widely thinking of. Chinese diplomats in unguarded moments have told American diplomats they wish to deindustrialize the USA, to turn us into an agrarian nation that supplies China and is essentially a vassal to it. Fuck that. Iran is part of the strategy to defeat that, not only for us but the free world and allies, as fair weather friends as some of them might be. We all have bitter memories of the GWOT, other long term missions or actions taken in the ME, we can legitimately be wary but we must be open that force is required yet again. The Korean War happened only 5 years after WW2, I’m sure the public was not happy with another war after fighting in the most destructive conflict ever but history waits for no one and reality is utterly remorseless, either we fight our enemies or we let them take what they want of the world.
