For the fourth time in ten years, China has blocked United Nations efforts to sanction Pakistan-based Jaish-e-Mohammed chief Masood Azhar. China’s decision came just weeks after a Jaish-e-Mohammed suicide bomber drove into a convoy of security personnel in Pulwama, India, killing 46. It also came in the midst of escalating tensions between Pakistan and India — South Asia’s rival nuclear powers. U.N. sanctions against Masood Azhar would not end the conflict, but it would deliver a powerful message about the global community’s resolve against violent extremism.

If the U.N. Security Council is unable to act, though, Congress still can.
