The US navy has announced that the USS Gerald R Ford, regarded as the world’s newest and largest aircraft carrier, has entered the area of responsibility of the US Southern Command, which covers Latin America and the Caribbean.

The deployment of the ship and the strike group it leads – which includes dozens of aircraft and destroyer ships – had been announced nearly three weeks ago, and its arrival marks an escalation in the military buildup between the US and Venezuela.

The regime of the Venezuelan president, Nicolás Maduro, meanwhile, announced what it called a “massive deployment” of land, sea, air, river and missile forces, as well as civilian militia, to counter the US naval presence off its coast.

Donald Trump has sought to justify the massive military buildup as part of his “war on drugs”, targeting traffickers allegedly smuggling narcotics through Caribbean and Pacific waters. That campaign has included airstrikes on boats that have so far killed at least 76 people in South American waters since September.
