I would have recalled my ambassador to Mexico immediately and would have appointed John Bolton as Secretary of Defense.
We'd be working overtime on SDI, putting Iran out of business and paying attention to our main SA ally: Colombia.
The Monroe Doctrine would be enforced and Cuber would be put on notice to load the Castro Brothers on a boat headed for Miami, or else!
We'd have to face the music as far as Russia and China is concerned and emphatically state that things will change or we'll have to have that showdown now. Too damned bad it didn't happen in 1945!
Then I'd put a padlock on both houses of Congress and tell them as Alberto Fujimori told his parliament: "Leave! You're getting in my way!"
Then I'd probably wake up from this pleasant dream.
I did enjoy your little dream!
I vote for you.
