As was widely reported in recent newstories, the U.S. army has destroyed several hundred million dollars of Daesh funds with their favorite method of conflict resolution, namely bombing the shit out of it. However, the destruction of U.S. currency is illegal under U.S. law, and, as was verified after the bombings, ISIS had a lot of their cash-reserves in actual dollar-bills. As soon as this became public knowledge, several prosecutors in the U.S. filed charges against the army. Within weeks, the U.S. was aflame with debate over the physical destruction of U.S. currency held by "enemy organisations".
The actual case is pending at the supreme court as of now, but Daesh has already prepared for a favourable outcome, equipping both their vehicles and their fighters with dollar-suits. As one of their leaders put it: "If they are taking this all the way to the supreme court when it's done by their army, you can be sure that they'll sue anybody else who does it."
