U.S. President Donald Trump’s second term is increasingly being shaped by an assertive and confrontational foreign policy, the BBC reported on Tuesday. This approach was dramatically underscored by the night-time raid in Caracas, during which Venezuelan President Nicolás Maduro and his wife were captured from their fortified residence.
While describing the operation, Trump openly distanced himself from the 1823 Monroe Doctrine, which asserted U.S. dominance in the Western Hemisphere, instead referring to it mockingly as the “Donroe Doctrine.” The move has triggered widespread concern over which countries could be next in Washington’s sights.
Greenland: Strategic Prize in the Arctic
The United States already operates a military facility in Greenland — Pituffik Space Base — but Trump has made clear that he wants control over the entire island.
“We need Greenland for national security,” Trump said, claiming the region is “covered with Russian and Chinese ships.”
Greenland, an autonomous territory within the Kingdom of Denmark and a NATO-linked entity, is rich in rare earth minerals critical for smartphones, electric vehicles, and military technology. Its strategic Arctic location is becoming increasingly valuable as melting ice opens new shipping routes.
Greenland’s Prime Minister Jens-Frederik Nielsen rejected Trump’s comments as “annexation fantasies,” warning that any U.S. military move would risk a direct confrontation with a NATO member, potentially destabilizing the alliance itself.
Colombia: Warnings After Venezuela
Just hours after the Venezuela operation, Trump issued a blunt warning to Colombian President Gustavo Petro, telling him to “be careful.”
Colombia, Venezuela’s western neighbor, is rich in oil and minerals and remains a key hub in the regional drug trade, particularly cocaine. Since September, the U.S. has intensified maritime operations in the Caribbean and eastern Pacific, alleging drug trafficking without publicly presenting evidence.
Trump has accused Petro of allowing drug cartels to “flourish”, imposed sanctions in October, and described Colombia as being run by “a sick man who likes to produce cocaine and sell it to the United States.” When asked whether Colombia could face a U.S. operation, Trump replied: “Sounds good to me.”
Iran: Threats Amid Protests
Iran is currently facing mass anti-government protests, and Trump warned that Tehran would be “hit very hard” if further demonstrators are killed.
Although Iran lies outside the traditional scope of U.S. hemispheric doctrine, Trump has repeatedly threatened the regime. Last year, U.S. strikes targeted Iranian nuclear facilities following a large-scale Israeli operation that culminated in a 12-day Israel–Iran conflict.
Reports indicate that Iran dominated discussions during a recent meeting between Trump and Israeli Prime Minister Benjamin Netanyahu, with new strikes in 2026 reportedly under consideration.
Mexico: Cartels and Border Pressure
Trump’s political rise was fueled by calls to “Build the Wall” along the U.S.–Mexico border. On his first day back in office in 2025, he signed an order renaming the Gulf of Mexico as the “Gulf of America.”
He has repeatedly accused Mexico of failing to curb drug trafficking and illegal migration, claiming drugs are “flooding” through the country. Trump has even offered to deploy U.S. troops on Mexican soil to combat cartels — an idea firmly rejected by Mexican President Claudia Sheinbaum.
Cuba: A Regime Under Pressure
Cuba, located just 145 kilometers south of Florida, has been under U.S. sanctions since the 1960s and maintained close ties with Maduro’s Venezuela, which supplied roughly 30% of its oil.
With Maduro removed, Cuba faces the risk of severe energy shortages. Trump suggested that military action may not be necessary, claiming “Cuba is ready to fall.”
U.S. Secretary of State Marco Rubio, whose family fled Cuba, warned Havana bluntly:
“If I were in the Cuban government, I would be worried — at least a little. When the president speaks, you should take it seriously.”
A New Era of U.S. Power Projection
The BBC concludes that Trump’s actions signal a dramatic shift toward unilateral power projection, raising concerns about international law, global stability, and the future of alliances such as NATO.
