The Iran issue with its new government after 1979 was one of the reasons why Carter's presidency was criticized so harshly by everybody, again, I do not think for a second that he 'brought' Khomeini to power in any way. The US aided the revolution like I said, but they didn't manage to install a pro US government, probably due to all the chaos.
The government of Iran stabbing women with needles in the forehead and killing kids for no reason sounds just like exaggerated nonsense propaganda to me, like them killing women who don't wear the hijab. Just know that Western medias have been trying to bring down Iran's government relentlessly since its creation, and stories like these are simply used as propaganda. Undoubtely women face significant issue in an Islamic regime, like in all other Islamic regimes, but I'd take with a grain of salt what you read in medias that are all owned by jews.
About Iran ever supporting ISIS, again I think that's also jewish propaganda. There is plenty of evidence pointing to Israel being the creator and funder of ISIS. ISIS never attacked Israel, they did just once by accident and they apologized lol. Israel even literally treated ISIS fighters in their own hospitals, just to send them back in the front lines. The crazy extremist ISIS attacked literally everyone, but when it attacked its master, it apologized. ISIS was actually Israel's attack dog, with the goal of attacking and doing terrorism against all of Israel's enemies in the region.
ISIS was a huge problem for Iran and they have been fighting it since forever, also because ISIS was exterminating followers of Shia Islam in the region, with all kinds of terrorism. Syria's new president, the anti-Iran jew, was literally an internationally wanted ISIS commander (the US had a 10million bounty on him), who killed hundreds, if not thousands of people, an actual true terrorist by defintion, but you have President Trump calling him a 'charming young guy'. At the same time the great Trump killed Soleimani, the man who actually played a crucial role in defeating ISIS, maybe out of spite because his beloved 'charming young guy' had to find another terror group to join.
