Regimes like Iran’s, be they theocracies or idealogical, are brittle past their initial installation. Being brittle, they must continually shore up their strength and suppress their opponents. Doing Friday chants against the Great Satan (USA) and Israel does little to make life better for the general populace.
Trump has been successful in this region in spite of the naysayers. He dropped the Iran Treaty as soon as he could, he avoided the tar baby of Syria, he is pulling back from the quagmire that is Afghanistan and now there is the UAE-Israel Peace Accord. None of these helps the Iranian Mullahs.
The thing about brittle governments is that they can appear strong right up to the break but once that happens they are in deep doo-doo. Russia will try to support them as Iran and Syria are its proxies in the region. China is there too and is trying to use Pakistan in that support. What a difference for those Shite Mullahs in the past 5 years, from Obama’s gift of Billion$ and a acceptance path to power but now misery in almost every direction!
If the Iranian Regime falls before the election, Biden will claim credit for it...
It is going to be a triumph for humanity when that brittle regime fractures, even if there is a brief, unpleasant period of bodies swinging from the lamp posts.
