阿富汗新战略出台后美国防部长首次出访阿富汗

U.S. Defense Secretary Jim Mattis landed in Afghanistan Wednesday on an unannounced visit – his first since the White House unveiled a revised plan for the U.S.-led war here.

Mattis landed in Kabul, his second stop on a South Asia tour that began in New Delhi.

President Donald Trump's Afghanistan plan, announced last month, envisions a greater role for regional players, including India, to help break the deadlock with Taliban insurgents.

During his stop in the Indian capital, Mattis praised India's “invaluable” contributions to Afghanistan, and welcomed “further efforts to promote Afghanistan's democracy, stability, and security.”

Mattis' Indian counterpart, Defense Minister Nirmala Sitharaman, promised to strengthen cooperation with Kabul, though he ruled out sending any Indian troops there.

The U.S. plan calls for a larger military presence in Afghanistan. Mattis recently announced the U.S. would send another 3,000 American troops, bringing the total number in the country to over 14,000.

Trump's plan also calls for more bombs. Official military figures show the U.S. dropped more weapons (503) on Afghanistan during August than in any other single month since 2012.

In a stalemate after 16 years of fighting, U.S. troops are involved primarily in a non-combat role, providing advice and assistance to Afghan defense forces and institutions.

Trump has stressed that the U.S. troops will only be withdrawn based on conditions on the ground, and has refused to set fixed withdrawal dates, as did his predecessor, Barack Obama.
