But it ISN’T. The US mainstream media constantly lies and the US pushes propaganda all around the world. We’ve been fed disinformation for decades not just since Trump. So I can’t just read up on them without a deep dive in trying to first find neutral sources and read and then evaluate them. If you just read the standard version about them your perception is going to be warped. Like I said, they have bad PR, which really means prevailing propaganda brands them as evil.
I don’t like their religious views either but fundamentally they are guys in a militia fighting against foreign invaders and threats to their country.
This is the ingrained propaganda that is clouding your understanding. Iran always complied (reasonably) with the NPT and seeks peaceful use of nuclear power. Just as Iraq didn’t have WMDs. These lies are framing their resistance and defense against imperialist aggression as aggression on their side.
Obviously Iran isn’t as nice and democratic, post racist and secular as the USA (/s) but they do have the right to defend themselves. Hezbollah is their tool. The US and Israel has theirs.
