“The director of the National Counterterrorism Center will step down next month, Biden administration officials said on Wednesday. The director, Christine S. Abizaid, has served three years as the country’s top counterterrorism official. In recent years, a resurgent China and Russia, as well as the wars in Ukraine and in Gaza, have replaced counterterrorism as the country’s main national security priorities. But speaking to a security conference in Doha, Qatar, last month, Ms. Abizaid warned that the Hamas attacks against Israel on Oct. 7, and the ensuing Gaza conflict, had energized an increasingly diverse set of worldwide terrorist threats. The Islamic State no longer controls vast swaths of territory in Iraq and Syria, but its fighters and groups aligned with Al Qaeda are on the march in Africa.”
