"The U.S. military base in Kosovo was constructed in 1999 without consulting with the government of Serbia and is the largest U.S. military base built outside of the U.S. since the Vietnam War."

Note: Kosovo declared independence from Serbia in 2008, so in 1999 Kosovo was still legally part of Serbia.
