A friend of mine worked for the Minnesota Irish Children's Fund for a while back in the 1980's. At the time he didn't know that the only time any Irish children ever saw that money was in recycling the shiny brass cases that the IRA would leave behind. My friend told me that he'd had his suspicions (a picture of the fund's director with men in ski masks tends to make one suspicious) but that he genuinely didn't know that the money was going to fund the IRA.
Whenever there is a prolonged conflict, someone has to be paying for all the bombs, guns, and bullets. I always figured that there must be Americans funding all sides in the Yugoslav wars.
