That's exactly it. They admitted supplying anti-government rebels with weapons.

Imagine a country comes and arm a group in the US to rebel against the government..

Wait, cites on the "US supplied Iranian protestors with weapons" bit? Other than Trump? It sounds ridiculous to question whether he's telling the truth, but here we are...

The USA didn’t turn Iran into a terrorist Jihadist state attempting to get nukes. Not everything is the USA’s doing, give extremely violent Islam its fault as well.

They certainly gave them a very hard push in that direction due to their coup in 1953. Do you also think 9/11 happened because of US freedom?

Iran is not a jihadist nor a nuke state. The US attempted to isolate Iran from the world, and tried to make everyone its enemy.

Iran has funded/stood up Hamas, Hezbollah, and Houthi rebels whose flags and charters include maximalist jihadist rhetoric. Iran my entire life has pushed 'death to America'. When Iran's leadership was killed they talked about welcoming it and Islamic martyrdom. My entire life that is my exposure to what an Islamic state looks like. Sure seems jihadist to me.

The only thing those groups have in common is their hate for israel. And israel has intentionally made them the enemy. As it has done with Iran. And blackmailed trump to go after Iran.

At this point you simply just back away from all indications of “iran bad”
