Live from Riga: Why not just say that the candidate is ignorant and underbriefed, rather than pretending that he is informed and briefed so you can try to play "gotcha"? You have a candidate who is trying to say that "the U.S. will not be a sap" and only that "the U.S. will not be a sap". But you push him into saying things that others will interpret very differently:
NYT: "[The Baltic Republics] are NATO members, and we are treaty-obligated..."
Donald Trump: "We have many NATO members that aren’t paying their bills."
