The BareStory
President Donald Trump has recently invoked the Monroe Doctrine in the context of discussions surrounding an incursion into Venezuela that occurred last week. The President stated that the 1823 foreign policy principle, while largely forgotten in recent decades, is now being applied to current U.S. foreign policy.
Historian Jay Sexton explains that the doctrine originated from a message by President James Monroe warning European powers to refrain from interfering in the Americas. While not originally a formal law, the policy evolved under subsequent administrations. President James K. Polk utilized it to justify the 1846 war with Mexico, which expanded U.S. territory. In 1904, President Theodore Roosevelt added a corollary arguing for preemptive U.S. action in Central America and the Caribbean to prevent European intervention and address instability.
According to Sexton, Roosevelt’s policy also aimed to protect U.S. business interests, leading to the deployment of Marines in roughly half a dozen nations. These interventions, known as the "Banana Wars," lasted until 1934. Sexton describes these operations as unpopular conflicts that resulted in hundreds of military deaths and tens of thousands of civilian casualties.
Following World War II, the doctrine was seldom mentioned in presidential discourse. However, President Trump has recently returned the policy to prominence, framing his administration's approach to the situation in Venezuela within the context of this historical principle.
How it may affect me
As a U.S. reader:
You may witness a shift in foreign policy where the administration uses this principle to justify preemptive actions or interventions to address instability in the Americas.
Renewed application of this doctrine could lead to military deployments intended to protect U.S. business and national interests, mirroring historical precedents in the region.
Potential military operations based on this policy carry the risk of service member casualties, as past interventions resulted in hundreds of military deaths.
Future interventions may prove politically controversial, given that historical operations under this doctrine were characterized as unpopular conflicts with high civilian casualties.
