You're trolling here, using an example of a threat ON RUSSIA'S BORDER (used only as ONE of the many possible [unlisted . . . these are short comments, not detailed articles] reasons for Putin's actions) to asking "So Putin can attack any country outside US . . ." -- Well, I didn't give Putin permission to attack Ukraine and I'm not saying he's doing the right thing. I DID say that I don't know ANYTHING about what's happening there; huge propaganda campaigns are coming from both sides. My point was basically if say, Russia or China were setting up bio-weapon labs in Mexico, Cuba, or Canada, would the US not do something about it? Of course we would (certainly under Trump), and you probably wouldn't complain about that. I sure wouldn't.
