Counterterrorism operations

President Trump has sent a letter to Congress detailing the countries where U.S. military personnel are deployed fighting the global war on terror.

"These ongoing operations, which the United States has carried out with the assistance of numerous international partners, have been successful in seriously degrading ISIS capabilities in Syria and Iraq," Trump writes. "If necessary, in response to terrorist threats, I will direct additional measures to protect the citizens and interests of the United States."

As to how long those deployments would last, the letter reads: "It is not possible to know at this time the precise scope or the duration of the deployments of United States Armed Forces that are or will be necessary to counter terrorist threats to the United States."

The letter describes U.S. deployments to or military strikes in Afghanistan, Iraq, Syria, the Arabian Peninsula, Jordan, Lebanon, Turkey, Somalia, Djibouti, Libya, Niger, Cameroon, Chad, Nigeria, the Philippines, Egypt, Kosovo and Guantanamo Bay, Cuba.
