Donald Trump said the US will begin land strikes on drug cartels in Mexico as he warned that the only limit to his global power is his 'own morality'. 

The president announced the military action against narcoterrorists just days after the capture of Venezuelan leader Nicolas Maduro. 

'We are gonna start now hitting land with regard to the cartels. The cartels are running Mexico, it's very sad to watch and see what's happened to that country,' Trump told Fox News Thursday night.

The president earlier boasted of his massive foreign policy powers when asked what the limits were on what the US military could do in the region. 

'My own morality. My own mind. It's the only thing that can stop me,' he told The New York Times. 

Trump has suggested that Greenland, Cuba and Colombia could be next on his list for US operations, angering NATO and world leaders ranging from the UK's Keir Starmer to France's Emanuel Macron.  

The president even interrupted his interview to take a phone call from Colombian President Gustavo Petro, who has promised he would 'take up arms' if Trump came after him.

Trump and his collaborators have flirted with the idea of invading or attacking the cartels in Mexico since his election campaign.

He has accused Central American drug traffickers of killing anywhere from 250,000 to 300,000 Americans each year, blaming it on the cartels' influence and fentanyl trafficking. 

'It's horrible, its devastated families, you lose a child or a parent. We've done a really good job, we're knocking it down,' Trump told Hannity.

Trump previously warned Mexico to 'get their act together' in the immediate aftermath of the capture of Maduro.

'You have to do something with Mexico. We're going to have to do something. We'd love Mexico to do it, they're capable of doing it, but unfortunately, the cartels are very strong in Mexico.' 

Trump and his collaborators have flirted with the idea of invading or attacking the cartels in Mexico since his election campaign.

Mexican President Claudia Sheinbaum has confirmed that the idea of US military intervention in Mexico has been raised repeatedly in her conversations with Trump, but said she has always rejected the offer.
