I’ve never understood this (your) line of reasoning: if what Russia does is ok because the USA does it, then the reverse is true—what the USA does is ok because Russia does it.
Never said it was ok. When someone complains about the offensive behavior of other countries, I simply point out we are doing it too. I think the worst was what the US and NATO did to Serbia. The Clinton war criminals go free without any complaint by the left all the while they are picking through east European counties charging nationalists with war crimes.
