US President Donald Trump's second term is being shaped by his foreign policy ambitions.
He's followed through on threats against Venezuela by capturing its president and his wife from their heavily fortified Caracas compound in a dramatic overnight raid.
When describing the operation, Trump dusted off the 1823 Monroe Doctrine and its promise of US supremacy in the western hemisphere - re-branding it the Donroe Doctrine.
Here are some of the warnings he's made against other nations in Washington's orbit in recent days.
Greenland
The US already has a military base on Greenland - Pituffik Space Base - but Trump wants the whole island.
We need Greenland from the standpoint of national security, he told journalists, saying the region was covered with Russian and Chinese ships all over the place.
The vast Arctic island, part of the Kingdom of Denmark, sits roughly 2,000 miles (3,200 km) to the north-east of the US.
It's rich in rare earth minerals, which are crucial for the production of smart phones, electric vehicles and military hardware. Currently, China's production of rare earths far outweighs that of the US.
Greenland also occupies a key strategic location in the North Atlantic, giving access to the increasingly important Arctic circle. As polar ices melt in the coming years, new shipping routes are expected to open up.
Greenland's Prime Minister Jens Frederik Nielsen responded to Trump by describing the notion of US control over the island as a fantasy.
No more pressure. No more insinuations. No more fantasies of annexation. We are open to dialogue. We are open to discussions. But this must happen through the proper channels and with respect for international law, he said.
Colombia
Just hours after the operation in Venezuela, Trump warned Colombian President Gustavo Petro to watch his ass.
Venezuela's neighbour to the west, Colombia is home to substantial oil reserves and is a major producer of gold, silver, emeralds, platinum and coal.
It is also a key hub for the region's drug trade - most notably cocaine.
Since the US began striking boats in the Caribbean and eastern Pacific in September - saying, without evidence, they were carrying drugs - Trump has been locked in a spiraling dispute with the country's left-wing president.
The US imposed sanctions on Petro in October, saying he was allowing cartels to flourish.
Speaking aboard Air Force One, Trump criticized Colombia's leadership, stating, He's not going to be doing it for very long.
Iran
Facing mass anti-government protests, Trump warned Iran that the authorities would be hit very hard if more protesters died.
Trump has previously threatened the Iranian regime with further action, with discussions about potential strikes against Iran following meetings with Israeli Prime Minister Benjamin Netanyahu.
Mexico
Trump's rise to power was marked by his calls to Build the Wall along the southern US border.
He has claimed that Mexican authorities aren't doing enough to prevent drug trafficking and illegal immigration, asserting that he may send troops to combat cartels - a move rejected by President Claudia Sheinbaum.
Cuba
With the fall of Maduro in Venezuela, Cuba may face significant oil supply challenges. Trump commented that military intervention may not be necessary, as Cuba appears to be ready to fall.
US Secretary of State Marco Rubio emphasized that Cuba's government should be concerned about the current situation and noted the importance of Trump's statements.
