The U.S. is claiming the right to prosecute anyone for anything they do anywhere in the world. They fined a French bank for violating U.S. sanctions against Iran that aren't in effect in France. Now they're prosecuting FIFA, The Fédération Internationale de Football Association, and is vowing to "end graft" in an organization that has nothing to do with the United States. If Europeans have any self-respect (they don't) they'll refuse to extradite.
What does the U.S. government care? Why are they vowing to "stamp out" alleged corruption that has nothing to do with us?
It might be because the World Cup tournament will take place in Russia in 2018 and because FIFA may finally take action against Israel for preventing Palestinian players from traveling to events, from getting needed equipment and preventing their full participation. Palestinians have petitioned for Israel to be kicked out of FIFA, so the Zionists are frantically trying to get support from other members.
They should kick the United States out, too.
