Retaliation
The Russian government has used military force to combat the rebels and Jihadists. Federal troops are still stationed there today. There are sporadic terrorists attacks, protests, and demonstrations. Well over 100,000 thousand people have died because of the two wars, terrorists attacks, etc. International groups have scarcely involved partially because of how hard it is for the press, media, etc. to gain access to the front lines. The U.N. has provided aid to the region. Also human rights organizations have expressed concern of violated human rights but that's about as involved as international organizations get. The U.S. has been obsolete in Chechnya. They have named a couple of leaders world terrorists but that's about as involved as they have gotten.
