Nothing.
This event just demonstrates the incompetence of Putin and his cronies. It is just plain stupid to leave weapons like these in the hands of people who don't know what they're doing and who don't care enough about the lives of innocent people to find out exactly what they are doing before intentionally shooting down what might be (and, in fact, was) a commercial jet.
There isn't any excuse or justification for any of this. Putin is just incompetent.
So it sounds similar to what the U.S. has been doing all over the world over the last few decades.
