Back at the time of the revolution in Iran, there was an interview on TV with some official in the new Iranian government. The interviewer, noting that the Iranian AF was comprised of American made planes and that parts for those planes were now embargoed, asked the official what they were going to do for spare parts. The official answered with disdain, (from memory only) “We are talking about American businessmen here...there will be no problem getting what we need.”
Like Jack Murtha says....There are many ways to influence someone.
Money for blood.
