What's happening there?

Why is the president focused on Greenland?

Is there a pressing national security issue at play here?

Or is this primarily about gaining control of natural resources?

Secretary of State Marco Rubio told lawmakers that Trump wants to buy Greenland, and Trump has said we can do this the easy way or the hard way.

How have Denmark and other NATO countries responded?

Could military action in Greenland effectively end the NATO alliance?

Francesca, let's turn now to Cuba.

For well over a century now, the U.S.

has maintained a military presence on the small island nation at Guantanamo Bay.

President Trump and Secretary Rubio have said Cuba is ready to fall.

Have they spelled out why the U.S.

is targeting Cuba?

We've previously covered the capture of Venezuelan President Nicolas Maduro and his wife.

The question of oil looms large here, though, and is definitely worth another mention.

Is the U.S.

looking at a long-term military occupation in the interest of big oil?

Venezuela isn't the only South American country on Trump's radar.

What's going on with Colombia?

Trump has also shown interest in the two countries we share our borders with.
