How could you think I called Iraq, Syria, Yemen, or Afghanistan stable? Oh well...
Iran has been largely stable even after the 1979 revolution. The Persians have no significant ethnic strife with the Balochis, the Lurs, the Mazanderanians, the Kurds, the Azeris (the Supreme Leader is Azeri), the nomadic tribes, or Iranian Arabs. It trains the largest military presence in the area, and it has had a historical influence on their part of the Middle East (including Iraq) since the dawn of civilization. Despite our sanctions, they have stayed together, improved their nuclear program, and they even sent living beings into space and back with completely homegrown technology. Aside from the occasional protests since ‘79 and the the Iran Iraq war, what has come close to compromising Iran’s stability?
That being said, if the people want to change the regime, let them do it according to their own ability and to their own framework, and with no outside influences, especially ones we try to sic on them. There are too many nefarious agendas in place who have an interest in destabilizing the Middle East.
Because you said so, and I quote,
“at least it is intrinsically stable in the region.”
I stand by for you to walk back your key assertion.
