U.S. Says Russia Tested Cruise Missile, Violating Treaty

The United States has concluded that Russia violated a landmark arms control treaty by testing a prohibited ground-launched cruise missile, according to senior American officials.

It is not the only violation of arms treaties by the Russians, but to my knowledge nothing has been done about the earlier violations which only encourages Putin to ignore the commitments of his predecessors.  He certainly had no problem ignoring the commitments made on Ukraine  territorial integrity.  What we see is a testing of little bites that will eventually lead to bigger ones and may lead to a major war in Europe and possibly have world wide implications.  His cruise missiles may be a part of such a war.
