There are two military factions in proximity to President Trump. One camp has the face of McMaster whose mentor is Petraeus. The other camp, the favored one, is that of Mattis.
McMaster is the White House insert of Petraeus and Petraeus is the Point man for the Senate Armed Services Committee (McCain, Linda, etc.) This the Neocon Camp that wants massive, neverending war because war is good, and it’s good for business; their business.
Mattis is the McArthur of the era. Efficient and timely. He has said he will take out NKorea in 15 minutes, and he won’t use nuclear. He will use space-based kinetic energy weapons, ‘Rods from God’.
A 15-minute war with NKorea would be absolute devastation for the Neocon Camp. We can bet they loathe Mattis.
I agree that Trump does NOT have to use anything nuclear.
We have plenty of ‘conventional’ weapons that can take out little Rocket Man.
