Speaking in a press conference on Tuesday, Secretary of State Rex Tillerson offered further clarity on the new American strategy in Afghanistan as put forth by President Trump in a major foreign policy speech on Monday night.

Saying that with a renewed commitment to the Afghan security forces doing battle with the Taliban, “we can turn the tide in Afghanistan,” and that a “conditions-based” military and diplomatic approach will change the dynamic on the ground.

Tillerson pointed to the campaign against ISIS in Iraq and Syria and the success the U.S.-led coalition has seen there in rolling back the terrorist group’s gains. From the State Department’s perspective, Tillerson says they must focus on eliminating the high levels of corruption that plague the Afghan government, and the U.S. can do that by holding their own systems and methods more closely accountable, specifically with regard to certain types of aid.

“As the security environment improves, we expect to adopt a different approach as to how we deliver on the development and assistance that supports the Afghan government,” Tillerson said.
