Following this morning's
brutal suicide bombings in the Moscow subway, the world's attention is once again turning to Chechnya. Since the 1991 collapse of the Soviet Union, the small Russian province in the outer reaches of the Caucasus mountains has been torn apart by cycles of warfare between the Russian military and separatist rebels. Though in 2009 Russia
declared the war officially over, a low-level guerrilla resistance still plagues the province, and Chechen terrorists have launched several high-profile strikes in Russia.
Monday's attack, the most violent in years, is generating global attention in part because most Chechens are Sunni Muslim, raising concerns that they would link up with Muslim terrorists in groups like al-Qaeda. Substantial connections between Chechen separatists and al-Qaeda have been difficult to prove, however, and the Chechen goal of independence would mesh poorly with al-Qaeda's aim of global Muslim rule.

So this is nothing new and Chechnya is apparently a breeding ground for terrorists and we continue to let these people in, they do not even have to walk across a border to get here. In fact we give them scholarships for heaven's sake.
