The hatred has been there since the 70s, at the very least. Watched a great video on Iran from Rick Steves filmed in 2009, and when he visited a mosque there was a large sign calling for the death of America and Israel.
For anyone saying that's dumb: it's not even true. Iran real issue with the USA started with the iran-iraq war, where Iraq had the support of the US, and used US-made chemical weapons against civilians.
"death of America and Israel" These are states. A particular instance of cooperating individuals, with some overall vector of behavior that affects people elsewhere. Wishing for that to end is hate how exactly?
I would not mind, and I actually wish america and israel and russia and few other states end as they are today (not just a mild refactoring, end and split to 10s of smaller independent entities, that can cause a lot less harm individually) and end up with reduced externalities on the rest of the world, and lot less power to walk over rest of us.
I don't even mind calling it death to america or whatever, because it would be. So why not.
The fact that you can rationalize those statements is a pure example of western self sabotage. Please leave your doors unlocked at night, leave food out for the raccoons and always trust in the kindness of strangers. Especially those expressing a desire of death to your vector of behaviour
Self-sabotage is comming from the top. Not from people on the bottom, who still have some lingering mild beliefs about justice or a desire to treat other humans in non-violent ways.
These Iranians are so evil they want to kill even love:
