The Contras were a terrorist group that terrorized Nicaragua and the USA government supported them. Iran was and still is our enemy, yet we sold them arms to help them in their war against Iraq. Some of the proceeds of the arms sales were diverted to Mr. North personally. He built a $50,000 fence for his house which he said was a necessity to protect him and his family from terrorists/bad guys. I am sure there are more details but that is what I remember about Iran Contra affair.
