The Trump Doctrine
Is the new Monroe Doctrine.
President Trump wants all of North and Central America under the USA.
And I am guessing he will tolerate absolutely no interference from foreign interests.
He is carving out our boundaries broadly enough to allow us to compete and win.
And while doing so he is respecting the sovereignty of other nations.
To the extent that he will allow Russia and China to annex pieces near them also, like Ukraine and Taiwan.
I think ultimately the USA will 'own' everything from the north pole to Panama.
Assuming the people of those nations choose to join.
Which I think they will.
