So pissed that the US tolerated a Soviet Brigade there for thirty years.
Who knows? Maybe Kennedy over-reacted (after all, he was a Democrat). Or perhaps the fact that the US and Cuba share a maritime border, and the US wasn't in a shooting war with Cuba when the Soviet troops arrived, somehow influenced the situation. In any case, I'm sure the Russians will be fine, if we move equipment (and maybe troops ;>) into Ukraine - heck, they'll probably offer to wash the road dirt off the vehicles, and throw our guys a barbecue...
