Trump’s do-nothing M.O. does seem to have taken on a pattern: Create a crisis, whip up the base, make a diversion (from our real problems), saber-rattle some, back down, claim victory (no matter what results), don’t apologize, then move on to the next issue.
Not sure it’s worked for: North Korea (no deal), Mexican tariffs (no tariffs), war with Iran (no crazy war yet), the census citizenship question (no question added), the border wall (no new wall built), etc., etc. It has, however, worked for much of his delusional base, as they seem to slurp-up the Kool-Aid.
Now that many sane folks are on to him, maybe he should change his M.
