WASHINGTON (Reuters) – President Donald Trump is considering significantly drawing down troops from Afghanistan, two U.S. officials told Reuters on Thursday, in the latest sign his patience is thinning both with America’s longest war and overseas military interventions, generally.

The U.S. officials, who spoke on condition of anonymity, said thousands of the 14,000 troops could be sent home as a result of the deliberations, the disclosure of which could undermine ongoing peace efforts with the Taliban.

The Pentagon declined comment. White House officials could not be immediately reached for comment.
