I'm not sure survival of the existing regime is high on the list of priorities of the average Iranian person at the moment...
And the subject of the thread is talking about Iran developing long range weapons and sending them and their drone technicians to Russia, which does not border Iran, in order to facilitate its war of aggression against Ukraine, which neither borders Iran nor possesses any credible threat towards it. The idea that when the US extends its military reach around the world it's an expeditionary force in foreign lands but when Iran does it has only the salvation of its people in mind is textbook anti-liberal double standards...
Syria isn’t Iran’s immediate neighbour. Neither are North Africa or Yemen, but there are natural strategic complements to Tehran having influence in each. Same as America. Again, same impulse, different scales. Iran is no Iceland.
The US is no nation governed by Angels, but orders of magnitudes "better" in most regards. Allies of the US fare much better than those of Iran or Russia. Its citizens have orders of magnitude more rights and access to self-fulfillment, among other things. The insistence on Israel not to get wiped out by an Iranian nuke is hardly a questionable goal.
Only the most black-and-white perspective can justify this false equivalency.
If you think Iran is such a good place, you should move there. As you can't see the moral difference between an imperfect democracy and an authocratic regime, you are certainly not capable of defending a democracy.
