What if President George Washington's warning to avoid international alliances and President James Monroe's "Monroe Doctrine" become the lasting centerpieces of American foreign policy?
I can see the Spanish-American War confined to Cuba and the Carribbean with no American involvement or interest in Guam or the Philippines. How does this influence world events, especially the rise of Japan?
How does this alter WWI if America remains an impartial neutral power and does not favor the Entente?
Lastly, how long can the US maintain this stance as the isolationist protector of the Western Hemisphere?
