Trump and the Western Hemisphere


Brief History of US FP in WH


‘Monroe’ Doctrine 

Outlined by President James Monroe in 1823

Early ‘spheres of influence’ doctrine where great powers would have their own spheres

Was focused on keeping further eu colonialism out of Americas

Was somewhat enforced by Britain which was the hegemonic power and ‘global cop’ at the time

Britain also wanted other EU powers out of Americas to promote free trade and British dominance


Roosevelt Corollary

More assertive addition on the Monroe Doctrine outlined by Republican President Theodore (Teddy) Roosevelt in 1904

US would intervene in countries within the Americas to maintain its interests

Reflected US as emerging great power and Roosevelt’s ‘big stick’ FP

Key examples - Roosevelt’s military support for Panama’s independence from Columbia

‘Gunboat diplomacy’ as US navy prevented Columbia from stopping Panama independence

Allowed for the building of the Panama canal and US control


Monroe Doctrine and Cold War

Focus shifted from European colonialism to Soviet communism

Aim was to keep Soviets and communism out of the Americas

Various presidents invoked the Monroe doc to justify US interventions


Cuba

1952 coup by military overthrows democratically elected government and installs pro-US Batista

Fidel Castro starts revolutionary movement against Batista

1959 Cuban revolution overthrows government and shifts Cuba to communism

Cuba exiles in Miami, FL are strongly anti-Castro and pro-Republican

1961 Bay of Pigs invasion by CIA-trained Cuban exiles failed

Cuban missiles crisis in 1962 and embargo since then


Rebels and Dictators

US focus on anti-communism led to support for anti-communist rebels and pro-US dictators to keep Soviets out

CIA coup in Guatemala

Contra rebels in Nicaragua

Pinochet in Chile, etc.


Panama

1989 US invades Panama

Arrested dictator President Noriega

Noriega exported drugs and threatened the security of the Panama canal


Venezuela 

In 1999, socialist government of Hugo Chávez elected

Strongly anti-US, supported Cuba and had growing ties with Iran

2007 Chávez nationalizes oil industry and takes assets of US oil companies

Chávez died and is succeeded by Nicolas Maduro

2017 starts shifting toward a dictatorship

2018 disputes election results and stays in power

Trump 1.0 imposes sanctions, embargoes, etc.




Realism, Multipolarity, Spheres of Influence

Preview: realism argues that hegemonic power carries the seed of its own destruction due to ‘imperial overstretch’

Hegemonic state provides global security, free trade, and foreign aid at the expense of its economy

Rival powers ‘free ride’ and catch up, creating a multipower world order

For realists, shift from hegemony to multipolarity requires a strategy of ‘spheres of influence’ and ‘containment/offshore balancing’

Spheres of influence means recognizing spheres of other great powers and staying out to avoid conflict and conserve resources.

Spheres of influence means pulling back bases, foreign aid, ect. from other spheres to slow overstretch and decline

Instead, priority is on maintaining influence on own sphere and keeping other great powers out

Can include ignoring wishes of smaller powers


Containment

Means preventing other great powers from getting too powerful and expanding outside their sphere

‘Offshore balancing’ means supporting allies in other spheres to balance against great power rather having own military in their sphere


Conservative Nationalism and Multipolarity

They want rollback

Conservative nationalism leans towards isolationism

It often draws on realist ideas related to restraint

‘Spheres of influence’ approach overlaps with nationalist focus on fewer bases, less foreign aid and fewer wars of choice

Aligns with other MAGA goals on immigration, resources, narcotics 


‘Donroe’ Doctrine

Trump adopted a Monroe doctrine spheres of influence approach in the 2025 National Security Strategy

‘Donroe’ Doctrine or the Trump corollary (similar to Roosevelt corollary)


1.Keep other great powers, specially China, out of the hemisphere

No military forces

No ownership or control of strategic assets and resources

No alliances with socialist govts


2.Ensure access to strategic resources

Oil and  critical minerals

Panama canal

Artic, greenland, northwest passage


3.Intervene in the Americas to:

Maintain borders prevent illegal migration

Prevent drug trafficking

‘Roll-back’ socialist governments


Donroe doctrine explains Trump’s actions towards:

Mexico and canada

Gulf of Mexico renamed to gulf of America

Venezuela and cuba

Greenland 

Others


Venezuela

US naval build-up, strikes on drug boats, oil tankers seized

Military operation to capture President Maduro

Regime remained but gave Trump control over oil

US oil companies returning and China pushed out


Greenland

Greenland is a key strategic location due to shipping routes, missile defense, minerals

US already has bases and Greenland would allow more

Trump wanted to add territory for legacy and used Venezuela operation to bluff


Cuba

Florida Cubans and neocons have long wanted Cuba

Blocking Venezuela oil and aid to Cuba was key

Trump and Rubio pressuring Cuba and leaders to make a deal
