President Trump received glowing praise Thursday from Afghanistan President Ashraf Ghani for the new war strategy, which was credited for turning around the 16-year war against Taliban militants and other radical Islamic terrorists.

“It is a difference of day and night,” Mr. Ghani said at a meeting with Mr. Trump. “The cloud of uncertainty has been lifted, but equally important is your commitment to a political solution at the end of this process.”

Mr. Trump announced the new strategy a month ago. It included setting long-term goals for the war effort, sending more U.S. troops to train and assist the Afghan military and revisions rules of engagement.

Before Mr. Trump took office, President Obama had begun a drawdown of U.S. troops and then halted the pullout as conditions deteriorated.
