You believe that one country soldiers can invade into other country, that didn't do a thing against them, can kill people, can burn buildings, because that country just decided something like that? You know what, this is what Hitler was doing at 1939 year. I don't remember ukranian being terrorist group that attack civil people in Russia. So this cannot be compared to USA actions. If next country after Ukraine will be Poland, Germany, France with same excuse, what will you say? Righ now we facing fact, that first time after World War 2 one country trying to conquer another country without even War Proclamation.
