LOL, sure, Putin invading neighboring countries in Europe(WW2 anybody?) for territorial annexation is the "right thing". Idiocy
Ukraine has the right to make any economic or military agreement, just like Finland or any another county in Europe.
In 2003 Putin and the Ukrainian president signed “Treaty Between the Russian Federation and Ukraine on the Russian–Ukrainian State Border”. It set Ukraine’s borders as they were in 1991 & was lodged with the UN.
But not Cuba. At least we didn't think so in 1962. Have we changed our mind about that sort of thing or are we simply monstrous hypocrites?
