President Obama made aggressive use of the CIA and Special Operations Forces to hunt and kill al Qaeda, ISIS and other terror groups.
But he also imposed a set of rules designed to regulate the conduct of U.S operatives — banning torture, for example, and minimizing the risk of civilian casualties in drone strikes.
President-elect Trump, who campaigned against those rules, would be able to undo most of those rules in his first hour in office, NBC News reported.
If he chooses to do so, Trump can quickly reshape large swaths of American national security policy, much of which is governed by executive orders and presidential policy guidance that can be overridden by the president's signature. That includes U.S. sanctions on Russia, and its recent rapprochement with Cuba.
