President Trump’s acting Secretary of Defense Christopher Miller sent a memo to his Pentagon staff that signals he could have been appointed to carry out troop withdrawals in places like Afghanistan or Iraq.

In the memo, dated November 13th, Miller addresses his staff for the first time and makes a strong statement against “perpetual war.”

“We are not a people of perpetual war—it is the antithesis of everything for which we stand and for which our ancestors fought. All wars must end,” the memo reads. “Ending wars requires compromise and partnership. We met the challenge; we gave it our all. Now, it’s time to come home.”

While Miller did not call for an end to a specific war, President Trump recently expressed his desire to bring all US troops home from Afghanistan by Christmas. Douglas Macgregor was appointed as Miller’s advisor this week, a retired U.S. Army colonel who has been outspoken in his belief that the US should immediately withdraw from Afghanistan.

President’s Pentagon shake-up that started with the firing of Mark Esper is rumored to have been done because of disagreements concerning troop withdrawals. Trump administration officials have told multiple media outlets that the president is still determined to bring home troops before leaving office.
