Pelosi has spoken to Mark Milley
Erecting a guard rail with the JCS in control has never been done before. During Nixon one had Schlesinger, and Kissinger still presiding.
Pelosi's best bet is to get agreement with Pence he will be the modern day version of Schlesinger, and Kissinger. Where the JCS should check with him, before launching ANY military action coming from Drumpf. Where there is no publicity about the agreement. If Drumpf finds out on 19-Jan, what's he going to do to Pence? LOL
If Pelosi is going to impeach Drumpf, she better get hoofing on it. He would avoid conviction a 2nd time. But it would be on the record, he was the only POTUS impeached twice. Nothing wrong with tarnishing his "name brand" for the future. He tried to take a dump on the Nation. Time for the Nation to take a dump on him.
