Vice President JD Vance has declared that an entire hemisphere belongs to America.

Weve been told for decades the U.S. military must go everywhere and do the impossible all over the world, Vance wrote in a post on X on Tuesday. But the red line for permanent Washington is using the military to destroy narco terrorists in our own hemisphere, he added, defending the Trump administrations military campaign against narco-traffickers, which has led to 22 alleged drug boats being struck in the Caribbean and claimed 83 lives.
