U.S. Taxpayers contributing to European Bailouts

The economic crises and riots in Greece, Portugal and Ireland and the impending crisis in Italy are major economic concerns in the U.S. It appears that American taxpayers are at least indirectly contributing to the bailouts of European governments who are reaping the consequences of huge deficits brought on by reckless spending and vote-buying. It doesn't make any difference who is in the White House, or who controls Congress, the more people find out about their own government the angrier they should get (e.g. Operation Fast and Furious).
