All the proof is in the other direction. The Iranian clerical establishment's Shiite imperial project is deeply resented by most of the population, its only support is among religious conservatives and the IRGC. Every indication we have is that the Iranian population's fondest wish is to go back to the pre-1979 days when Iran was Israel 2.Compared to these examples what proof do we see from Iran that shows hey have the moxie to be a pole in the multipolar world?
You're making our point. No one questions that Iranians would fight to defend their homeland, but Iran would and is folding when its Arab allies and co-religionists are put under pressure.I'd say Iran has proven it's willing to sacrifice for its own lands. But Arabs are not Iranians.
As far as an Iranian nuclear weapon goes, I'll use an American idiom I really like: shit or get off the pot. Either Iran fully embraces the North Korea life and tests a nuclear weapon, or it waves a white flag and abandons its foreign ambitions. The Iranian president, as weak as I consider him, has at least picked a side.
