We in Russia fight Chechens for 200 years and can't win. Why US allow them and people of related nations enter and live is beyond me. They are bandits and have always been.
The same happens in Russia with uneducated Middle Asia migrant workers. Except they are not terrorists. Yet.
Sorry, but I don't believe in existence of 'good chechen guys', especially young. Their mom knew everything from the beginning and must shut up.
