Maybe the USA is stepping back and taking a different approach. Look at the recent happenings in Venezuela.
Maybe the USA is violating international law, i.e. The Geneva Conventions, in which we agreed not to assasinate leaders of other nations.
And another point you're confused on is that we have created the monsters that need "offing". And sure, it would be expedient to get rid of them.
And I am not sure what you mean by Venezuela. If you mean, democracy in action, free from CIA interference, I agree, it's a miracle.
