Interesting theory, troll. I think you are at least partially right in what you say. The USA has been trying to "take out" Iran ever since the Iran hostage crisis in Jimmy Carter's term of office. The first plan was to get Iraq to do it, in the 80's...but Saddam failed. His attack on Iran turned into a bloody stalemate. He then, in effect, became a liability from the American point of view.

The USA and Iran have been out to get each other for a very long time. It's an old grudge match. The USA interfered in Iran (way back in the 50's was it?) and set up the Shah. The Shah became hugely unpopular and was finally overthrown. The Mullahs who took over kidnapped a bunch of Americans and held the USA to ransom. Reagan arrived at an agreement with them (they may have been scared of what he might do...he had a reputation of sorts...). The USA then armed Iraq to destroy Iran. It didn't work. And so it goes...

There really are no good guys in this sordid little story of power politics, except for the ordinary people on all sides who suffer and die as the big game is played out.
