It's insane how these people simp for Iran. Completely unable to be reasoned with because they hate jews so much
Whilst that's definitely a component; it's not like they haven't earned some ire, they are to Americans what Pakistanis are to Brits, a group who are self-interested to the detriment of the majority and get away with far more than they ought to with too little blame from the establishment and society, but it's not the sole reason (and Jews tend to be more financial and mental rapists over actual rapists, but then again:
Hollywood, so...).
The way I see it, it's precedent of past events coupled with some knowledge of history.
"Iran is a massive funder of global terror!" "Like the Saudis were?"
"Iran is
this close to possessing nuclear bombs!" "Like the Iraqis and their WMDs?"
"Iran says they want to destroy us!" "Like North Korea?"
"Iran is primed to enter conflict with the US at any moment!" "Like China would if they invaded Taiwan?"
"Iran cannot be allowed to gain greater influence in the area!" "Like Russia did in Ukraine/Iran?"
"The Ayatollah must be removed!" "Like Assad/Gadhafi?"
I think rather than being in tacit support of Iran, arguing against any involvement at all just makes it appear that way in happenstance. Acting in one instance (Iran, Afghanistan) yet being inactive in others (Saudis) doesn't translate into it being a truly pressing issue, and whilst context for some matters (North Korea is a Chinese puppet state in all but name) the silence around other instances but not others seems very blatant. Being aware of stuff like AIPAC just makes the motivation for US involvement at all look suspect because you have a group who throws money around for the tacit purpose of promoting Israeli/Jewish interests.
There's also the possible worry of long-term consequence. Syria's civil war coupled with Isis (remember those guys?) and the intervention in Libya lead to mass immigration of Arabs, Turks, and Africans into Europe on mass, which in turn yanked the socio-political chain leftward, which is only just now starting to return to the centre (or seeing a similar albeit slower yank to the right). but a consequence of that yanking helped contribute to many the West's current political woes; it certainly helped to fuck up the internet considering the mass suppression of migrant news on social media and the Western government's complicity in doing so.
If there's any greater involvement from the US, it might force changes in discourse and create further political estrangement/resentment that could prompt something bad down the line. An unintended consequence of of reactive American involvement in the Middle East is what lead to them taking the role of policeman over the region to begin with:
You can trace the US feeling obliged to help Israel from displacing their former supporters (France and Great Britain) during the Suez Crisis, and the subsequent wars with Israel thereafter to the Arabs perceiving an isolated and vulnerable Israel. If America was as influenced by Jewish interests back then as they were today, maybe they wouldn't have done this? Israel would own the Sinai and probably have a dumping ground for the Palestinians, but that's speculative.
Yes, there's reason to oppose Iran, but we still can't be certain of how much of that is just false information, supporting Israeli interests, and a overreaction to rhetoric that other countries have espoused previously. How much of that rhetoric and anti-Americanism is the result of supporting Israel over just existing?
A portion of Osama Bin Laden's statement on 9/11:
I say to you, Allah knows that it had never occurred to us to strike the towers. But after it became unbearable and we witnessed the oppression and tyranny of the American/Israeli coalition against our people in Palestine and Lebanon, it came to my mind.
The events that affected my soul in a direct way started in 1982 when America permitted the Israelis to invade Lebanon and the American Sixth Fleet helped them in that. This bombardment began and many were killed and injured and others were terrorised and displaced.
I couldn’t forget those moving scenes, blood and severed limbs, women and children sprawled everywhere. Houses destroyed along with their occupants and high rises demolished over their residents, rockets raining down on our home without mercy.
The situation was like a crocodile meeting a helpless child, powerless except for his screams. Does the crocodile understand a conversation that doesn’t include a weapon? And the whole world saw and heard but it didn’t respond.
In those difficult moments many hard-to-describe ideas bubbled in my soul, but in the end they produced an intense feeling of rejection of tyranny, and gave birth to a strong resolve to punish the oppressors.
And as I looked at those demolished towers in Lebanon, it entered my mind that we should punish the oppressor in kind and that we should destroy towers in America in order that they taste some of what we tasted and so that they be deterred from killing our women and children.
And that day, it was confirmed to me that oppression and the intentional killing of innocent women and children is a deliberate American policy. Destruction is freedom and democracy, while resistance is terrorism and intolerance.
This means the oppressing and embargoing to death of millions as Bush Sr did in Iraq in the greatest mass slaughter of children mankind has ever known, and it means the throwing of millions of pounds of bombs and explosives at millions of children – also in Iraq – as Bush Jr did, in order to remove an old agent and replace him with a new puppet to assist in the pilfering of Iraq’s oil and other outrages.
So with these images and their like as their background, the events of September 11th came as a reply to those great wrongs, should a man be blamed for defending his sanctuary?
Is defending oneself and punishing the aggressor in kind, objectionable terrorism? If it is such, then it is unavoidable for us.
This is the message which I sought to communicate to you in word and deed, repeatedly, for years before September 11th.
TLDR: It's not: Iran > Israel. It's Iran = Israel, and neither should make America act in a way that's detrimental to its own citizens.
