Donald Trump to begin land attacks on Mexican cartels and warns only limit to global power is 'own morality'

There is growing pressure on Mexico's President Claudia Sheinbaum to forcefully crack down on drug cartels and criticism from opposition leaders that she isn't doing enough to address insecurity in the country.

Now, Mr Trump is once again talking up his foreign policy stance as he laid down the gauntlet to President Sheinbaum.

The US President told Fox News: "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.'

"It's very sad to watch and see what's happened to that country."

In the middle of his interview with Fox News host Sean Hannity, President Trump received a phone call from Colombian President Gustavo Petro, who has promised he would "take up arms" if the White House came after him.

When asked in a separate interview by the New York Times if there were any limits on his global powers, Mr. Trump said: “Yeah, there is one thing. My own morality. My own mind. It’s the only thing that can stop me. I don’t need international law...I’m not looking to hurt people."

President Trump's foreign policy has come into the spotlight following the capture of Venezuelan leader Nicolas Maduro as well as his desires to possess Greenland.

When asked why the US needed to possess the territory, he said: "Because that’s what I feel is psychologically needed for success.

"Ownership is very important. I think that ownership gives you a thing that you can’t do, whether you’re talking about a lease or a treaty.

"[It] gives you things and elements that you can’t get from just signing a document."

Overnight, President Trump announced had canceled a previously expected second wave of attacks on Venezuela following cooperation from the government in Caracas.

He said the US and Venezuela were working well together, adding that at least $100billion would be invested by the "big oil" companies in Venezuela.

He added, however, that all oil tankers in Venezuela "will stay in place for safety and security purposes".

Venezuela, with the world's biggest proven oil reserves, has become impoverished in recent decades, with eight million people fleeing abroad in one of the world's biggest migration crises.

Washington and the Venezuelan opposition have long blamed corruption, mismanagement and brutality by the ruling Socialist Party on the crisis.

Ousted President Maduro blamed the economic damage on US sanctions.

Later today, President Trump is scheduled to meet with the heads of major oil companies Exxon Mobil, ConocoPhillips and Chevron at the White House to discuss ways of raising Venezuela's oil production.

The companies, all of which have experience in Venezuela, have declined to comment.

In Mexico, opposition parties have slammed President Sheinbaum's security strategy, highlighting the high number of politicians killed in office.

According to the Mexican NGO Common Cause, 56 politicians were killed last year, including seven sitting mayors.

In November, Carlos Manzo, the mayor of Uruapan in Michoacan, was assassinated in a case that shocked the country.

According to security analysts, seven of Mexico's 32 states account for just over 50 per cent of homicides nationwide, led by Guanajuato, Sinaloa and Baja California.

Senator Mario Vázquez of the opposition conservative PAN party said: "Mexico needs strong local police forces, with support and resources.

"The government must listen to those who face violence in their communities every day. Mexico deserves real security, not speeches."
