This report is worth reading. The war fever being stoked by Trump is not matched by any change in U. S. military actions or preparations. Also, "Hey Man"'s observation is entirely correct. Supposedly sober types like General Mattis speak casually of the genocidal destruction of the entire population of North Korea as though it were simply a technical matter.
Meanwhile, it appears Trump will offer Joe Manchin a cabinet job, allowing the newly declared Republican governor of West Virginia to appoint a Republican replacement, after which the Senate can pass their horrendous health care bill. This is monstrously bad news.
