"Is this a big deal considering what the USA has done in North Korea, Vietnam, Libya, Afghanistan, Iraq and other invaded countries."

I remember fine, not about N. Korea though, but the torture techniques were sort of tame compared to ehat the Russians are doing right now, It occurs at you sure are forgiving towards Russia right now. Makes me wonder about your nationality. It seems that no matte by an Amerivr what war crimes they commit you excuse it because of some crime committed by an American in the past that, in many cases, was a crime punished for by our own government. The U.S. is certainly not perfect but the things Putin is doing in Ukraine are not justifiable by lame comparisons to crimes committed by anyone else. They are targeting apartment buildings, schools and hospitals every day and, so far, without a comparable response from Ukraine but I doubt that will hold true much lomger.
