President Trump has given the Pentagon new power to decide the number of U.S. troops in Afghanistan, meaning thousands more U.S. soldiers could be deployed. The authorization came the same day Defense Secretary Jim Mattis testified to the Senate Armed Services Committee.

Defense Secretary James Mattis: “We are not winning in Afghanistan right now, and we will correct this as soon as possible. I believe the three things we are asking for stand on their own merit, however, as we look more broadly at the protection of the country.”

There are currently about 8,400 U.S. troops in Afghanistan. The war in Afghanistan is the longest war in U.S. history.
