Trump administration says it has taken action against 26 people ‘across our hemisphere’ who allegedly undermined US interests.

The State Department in the United States has announced it is restricting visas for “individuals from countries in our hemisphere who support our adversaries in undermining America’s interests in our region”.

Thursday’s statement underlined that 26 individuals had already seen their visas stripped as part of the policy.

The State Department’s stance comes as President Donald Trump seeks to expand US influence across the Western Hemisphere, as part of a platform he calls the “Donroe Doctrine”, a riff on the 19th-century Monroe Doctrine.

Since taking office for a second term, Trump has taken an aggressive stance towards stopping drug trafficking across the Americas, threatening economic penalties and military action for noncompliance.

He has also sought to check China’s growing sway over the region, as an increasing number of Latin American countries tighten their bonds with the Asian superpower.

The State Department explained that the expanded visa restrictions would penalise those who “knowingly direct, authorise, fund, or provide significant support to” US adversaries in the Western Hemisphere.

“Activities include but are not limited to: enabling adversarial powers to acquire or control key assets and strategic resources in our hemisphere; destabilising regional security efforts; undermining American economic interests; and conducting influence operations designed to undermine the sovereignty and stability of nations in our region,” the statement added.

The language was vague, never mentioning China or the campaign against drug-trafficking cartels.

But it continues a trend under the Trump administration to revoke visas from foreign critics and political opponents.

Last year, for instance, the administration sought to revoke visas for pro-Palestine protesters, claiming their presence could have foreign policy consequences for the US.

More recently, the administration has terminated the immigration visas for at least seven individuals with familial ties to the Iranian government or individuals connected to the 1979 Iranian revolution.

Revoking visas

The statement on Thursday did not identify the 26 individuals facing visa restrictions as part of the expanded policy.

But it cited the same authority under the Immigration and Nationality Act that the Trump administration has used to attempt to deport pro-Palestine student protesters last year.

Under the law, the entry of foreign nationals can be restricted when the secretary of state has reason to believe they pose “potentially serious adverse foreign policy consequences for the United States”.

While the administration has abandoned deportation efforts against some of the targeted individuals, at least two, Mahmoud Khalil and Badar Khan Suri, continue to face expulsion.

More recently, the administration has terminated the immigration visas for at least seven individuals with familial ties to the Iranian government or individuals connected to the 1979 Iranian revolution.

Already, some figures in Latin America have seen their visas revoked over political disagreements with the US.

In July, Brazilian officials involved in the prosecution of former right-wing President Jair Bolsonaro saw their US visas withdrawn. They included Brazilian Supreme Court Justice Alexandre de Moraes, a frequent target of right-wing ire.

Then, in September, the Trump administration stripped Colombian President Gustavo Petro of his visa after he made an appearance at the UN General Assembly that was critical of US policy.

The State Department, at the time, denounced Petro for “reckless and incendiary actions”. He was later invited to visit the White House in February, as part of a detente with Trump.

Visa restrictions have been part of Trump’s larger policy to exert pressure on foreign groups and limit immigration into the US.

Earlier this year, the administration enacted immigrant visa bans on dozens of countries, citing both national security and alleged stresses on social services.

Trump has also sought to take a more militaristic approach towards Latin American governments it deems as adversarial, referring to the whole of the Western Hemisphere as the US’s “neighbourhood”.

In January, the US launched an attack on Venezuela that culminated in the abduction and imprisonment of Venezuelan leader Nicolas Maduro, and it has also initiated an ongoing fuel blockade against Cuba.

Some of Trump’s actions in the region have been deadly. The Venezuela attack left dozens of Cubans and Venezuelans killed. And since September, the Trump administration has conducted at least 51 lethal strikes on alleged drug-smuggling boats in the eastern Pacific Ocean and Caribbean Sea.

The death toll in that campaign has reached at least 177 people. Rights groups have decried the attacks as extrajudicial killings.

But the Trump administration has labelled multiple drug cartels as “foreign terrorist organisations” and has argued they are seeking to destabilise the US through the drug trade.
