The US & UK supported the 1953 coup d'état to secure their oil interest. "Economically, American firms gained considerable control over Iranian oil production, with US companies taking around 40 percent of the profits" The Islamic Revolution is a response to this. If the west wasn't as imperalist, who knows what could've become of Iran.

But to be honest, there's no way western forces will take over control in Iran. Though it's at a technological disadvantage, their military is huge, as well as their population of more than 90 million. Then there's Pakistan that has threatened to get involved if the US does. Then there's Irans proxies, though they're in a relatively weakened state for the moment. But Iran has allied millitias all across the region. Then there's China depending on the Iranian oil. I mean, if you want to force your way into World War 3 this seems like a brilliant idea.

Like vampires, but instead of blood, they suck oil.
