The notion that Iran's military threat exclusively down to antagonism of Israel is another conspiracy theory - because their actions clearly are much broader.
The concern over Iran is founded in the fact that since their Islamic Revolution, they've been an open antagonist of the US and the West, they constantly threaten the Gulf, Saudi Arabia, the stability of the Middle East. Since they have embarked on their Nuclear Program which they are using to Blackmail the world, it's become a much more significant issue.
Iran's 'problem with oil' is not their ability to supply, it's that they are literally attacking Saudi Arabia both directly and indirectly (via Houthis) and trying to overthrow House of Saud, Bahrain, and eventually the other Gulf states. They're constantly threatening commerce (mostly Oil) in the Gulf.
This antagonism by the way is rooted in centuries-old Shia vs. Sunni conflict over the righteous claim to 'True Islam'.
Iran's destabilizing and support of terrorism against Israel is of course well founded, but their actions against Saudi Arabia are more direct and have much bigger direct repercussions. Of course, the overthrow of Israel has probably the most indirect knock-on effects which would throw the entire region into chaos.
And by the way 'Big Business' in the world would much prefer to end sanctions. All of that Iranian Oil will be spent on US and German 'stuff' and Tim Cook would definitely want to sell them all iPhones.
Protection of individuals privacy, so that their emails and SS numbers aren't accidentally made public, are basically an orthogonal issue - not even business issues are aligned.
This talk of a nebulous 'overclass' is not helpful to your argument if you conflate their own needs especially 'money' - which most of them wold prefer to make in Iran if they could. The US has a complicated leadership class that's not easily lumped into groups. We're seeing more progress on issues of privacy so cross your fingers.
