Why is the US or NATO justified in doing the same to Russia then ?
[Edit] Since the algo won't let me post too many comments too fast.
Sanctions/War/whatever . . . the point is that the actions of the United States in Iraq, Afghanistan and Syria are many orders of magnitude worse than anything Russia has done to Crimea or is planning on doing to Ukraine, so any retort saying "We are not going to war, we are applying sanctions" is about as paradoxical as it gets.
If those actions justify sanctions or war, surely the US should be first in line to sanction itself?
