So, Trump (or at least his most trusted advisor) felt it OK to act as a President, and go around his own intelligence agencies to create a secret channel to an adversary, what will he do after being President?
Set up his own private channel?
Continue to leak secrets from our allies (no, post presidents do not have the declassification power.)
Alienate allies regardless of cost?
Use his reputation to increase the value of licensing his name?
“Take this plane to Moscow?”
Have taxpayers continue to finance his buildings, his travel, and his security?
Undercut his successor has he has tried to do his predecessor?
Bottom line. There has to be a strategy to keep him under tight control.
