What you're doing, is observing a r_pe in progress - and then saying that you hate the victim and the r_pist equally.
Firstly, Iran didn't do anything in 1988 - but kill some CIA-Backed TERRORISTS (from the MeK CULT) who were engaging in organized TREASON.
Iran was attacked by Iraq, with Chemical weapons, that the US' Empire GAVE to Saddam Hussein's Iraqi Government, and put him up to using against them. The MeK were fighting on the Iraqi side. They are universally despised within Iran.
The US history of abuses against Iran go back at least to 1953, when we overthrew their lawful Government (OPERATION AJAX) and then installed a brutal dictator over them, and trained his secret police in torture and oppression.
Then when people rose up to overthrow the Shah - the CIA, MI-6 and Mossad collaborated to ensure that his Government was replaced by a conservative theocracy. They broke the Ayatollah Khomeini (the predecessor of the guy they just killed) out of house arrest - and sent him to Paris, by way of Iraq. While in Paris they propagated his speeches back into Iran, using the BBC's shortwave Farsi radio. service. They were afraid of the leftists and college students, who'd largely been behind overthrowning the Shah, gaining power in the Revolution. So they backed the Shia Clerics, since that's the largest religion in the country. They were likely involved in the 2nd break-in at the US Embassy, and the ensuing hostage crisis that embarrassed Jimmy Carter, and handed the election to Reagan.
They Mullahs are popular, and it prevented any alliances or fraternization with the USSR. They're still overwhelmingly popular amongst Iranians - even moreso, now that we've made Khameini a martyr.
It doesn't really matter if you're a Zionist - Trump and the US Congress is, undeniably. So not actively opposing Zionism is tacit support. Doing nothing on a moving train isn't being neutral.
