Strengthening Tools to Counter the Use of Human Shields Act This bill extends the authority of the President to impose sanctions on foreign persons using human shields through 2030 and requires the President to impose such sanctions on each foreign person determined to be a member of Palestine Islamic Jihad and orders, controls, or otherwise directs the use of human shields. Currently, such sanctions are (1) required for users of human shields who are members of Hamas or Hezbollah or supporters of those groups, and (2) authorized for other users of human shields. The President must also determine if a person named in certain congressional requests meets the criteria for such sanctions and report on whether the President intends to impose sanctions on that person. Additionally, the Department of Defense must report to Congress on the implications of the use of human shields by Hamas, Hezbollah, and Palestine Islamic Jihad.
