I still don't understand your point but ok.
the point is iranians are always looking for execuses.
excuses such as Shah Fell because Carter did not support him.
Mosadegh Fell because Americans backstabbed him.
America Rejected Iran's cooperation in Afghanistan Arena and put Iran in Axis of Evil.
America went back on it's promise on JCPOA.
Well the reality is International relations is not about fairness.
Iran has been fighting about its weight class for a quite a while (by having a very effective long term military strategy).
however, Iran has totally neglected political development (Political reforms in iran have been way too slow, given that the movement started 20 years ago)
Most importantly, Systematic (society wide; not just government) culture of corruption has seriously hampered iran's economy.
That said iran will probably barely survive this. But it will get worse before it gets better.
That's because Iran's only way to get beyond this is probably to go more defiant, build more x, y ,z. so they have
some options to push back when they get back to negotiating table.
That is assuming every stays constant. which is rarely does; Trump can be impeached (unlikely), Khamenie can die, Massive Earth Quake in Tehran..
