Fair enough. I just think people too quickly frame these issues as "accept X policy consequence or you support the worst-case scenario." Reality is usually more complicated than that.
And since you asked...I don't support a nuclear Iran & I don't think most people questioning this strategy do either. My issue is acting like the only options are "support escalation" or "support Iran getting nukes." ...again, binary choices where there is nuance. I am so tired of the Sith mindset.
This also isn't new information. We've known about Iran's nuclear ambitions for decades. That's why things like Stuxnet, sanctions, covert operations, sabotage, intelligence operations, etc. have been used for years to slow their program rather than jumping straight into another large-scale ME conflict. Stuxnet alone damaged or destroyed a significant number of centrifuges at Natanz without an invasion.
Frankly, I'd be more supportive of ops specifically aimed at degrading Iran's ability to fund and coordinate terrorism through proxies than broad "shock and awe" style crap justified primarily through nuclear rhetoric.
Speaking of shock and awe, watching this mess unfold feels uncomfortably reminiscent of the lead-up to OIF...not necessarily identical circumstances but similar over-confidence that overwhelming US military power automatically translates into strategic success. We had no idea what the heck to do with Iraq after we "won the war."
So the issue then becomes have we learned anything about the ME over the last 20+ years. It's looking like we haven't learned a dadgum thing.
