> That doesn't make sense for America to care about this much, given that Iran has no way to deliver nuclear weapons to it.

A nuclear armed Iran could hold oil and gas shipments in the Straight of Hormuz hostage indefinitely. It could also threaten U.S. bases and warships in the area. It could threaten regional allies with a nuclear attack.

Irrespective of everything else going on, it’s well established that Iran has a nuclear program in the advanced stages of development. There was a whole UN program around inspecting it.

Personally, I don't care about the profit margins of oil and gas companies, and I will vote against any politician that partakes in sending my fellow citizens to die for the profit margins of oil and gas companies.

I also don't particularly care about the plight of regional allies, particularly ones that have a bizarre tendency to constantly poke the bears around them.
