Agreed. You have to wonder at people who complain about Trump acting this way. It's just a matter of "You slap me, I punch you." Would they rather Trump be like GW and just take it? How well did that work out?
Bush should have addressed what was being said and didn't.
Trump is threatening people. That's a BIG difference!
You address the message. You don't threaten the messenger. KGB tactics anyone?
