Uh...wasn't it Reagan who's shadow government was responsible for the Iran-Contra Scandal? Carter tried to solve the Iran problem without kowtowing to the Iranians; Reagan's group treasonously sold arms to the Iranians and used the money to illegally fund the Contras in Nicaragua.
As far as Reagan is concerned, he may not have known about the arm sales, but then again he also couldn't distinguish between being a real tail gunner during WW II and just playing one in the movies. Reagan, George W Bush, and the current "President" have been the worst US Presidents.
Mr Carter and Mr Obama will go down as two of the greats who rescued the US from demise under disastrous Republican administrations.
