That's been the status quo for decades, but between Trump convincing folks that the US won't protect them and Iran convincing folks that the US can't protect them, and Hegseth focusing more on culture war stuff rather than policy objectives it's a guarantee that's looking a bit thin.
Iran isn't convincing anyone. It's a rogue terrorist state that has pissed off all of its neighbors by launching missiles at them and harassing their ships in international waters. The country is sinking, inflation and unemployment are rampant, its currency is worthless, but the mullahs will do whatever it takes to stay in power.
