US President Donald Trump has signed an executive order instructing the secretaries of state and treasury to review whether certain chapters of the Muslim Brotherhood should be designated as terrorist organizations. The process will involve a detailed report on chapters in Lebanon, Egypt, and Jordan, with potential designations as Foreign Terrorist Organizations or Specially Designated Global Terrorists. The White House claims these chapters have supported attacks against Israel and US allies, and the order aims to disrupt their operations and resources. Notably, the order does not address chapters or organizations in Qatar and Turkey, despite their known ties to the Brotherhood. The impact and enforcement of the order remain uncertain, but it is expected to deter organizations from engaging with Brotherhood-linked groups worldwide.
