Geoff Mulvihill writes at AP:

Five Muslim immigrants face possible life prison terms after being convicted of plotting to massacre U.S. soldiers in a case that supporters called entrapment and prosecutors said was a pre-emptive strike against terrorism.

The five men were convicted Monday in federal court of conspiring to kill military personnel but acquitted of attempted murder. Prosecutors acknowledged the defendants were probably months away from an attack at Fort Dix and did not necessarily have a specific plan.[5 immigrants face life behind bars for Army plot, December 23, 2008]

I suspect this is just the tip of an iceberg. These guys don't appear to be serious conspirators. However, there are real potential issues with a diverse military. A lot of old scores can get settled on a battlefield or in other aspects of the military.

If I were a strategist for a major terrorist organization, infiltrating the US military and key parts of US infrastructure would be high on my list of priorities. Muslim organizations have been up against the Mossad for decades now—and I suspect they've learned quite a bit from that process. I doubt we'll understand what is really going on here until it is too late.
