Fact is that once the US starts to talk to the Hezbollah, or the Ayatollahs, then people's imagination will not ride wild. People will then be able to see and feel the debates with the Hezbollah and the Ayatollahs, and the "fear factor" would be diminished.
So who benefits from this "fear factor"? Well the US forces themselves. With no fear, then there would be no need for the US forces in the area. The US military budget needs to be maintained.
"The U.S. should break with long-standing policy and start talking to Hezbollah in order to "mess with" the Iranian-backed group, a leading U.S. expert on the Mideast told Congress on Tuesday."
