If it is true that Hezbollah is setting up shop in Mexico, the Obama administration had best hope they lose (and lose it quickly) their law suit against Arizona's new immigration enforcement law.
It doesn't even matter if that type of enforcement would have caught jihadi terrorists if they enter America and carry out an attack. What will matter is that the story will be that the administration didn't think enforcement of southern border security was much of a priority for them in 2010.
Let's hope this issue remains one of domestic politics.
