The concept of a physical security island is quite interesting; this move by Pakistan has added a moat to the negotiation table.

The Pakistani capital Islamabad began enforcing a heavy vehicle entry ban into the city at dawn, with upgraded control at long-distance bus stations and shortened operation times for the metro and buses. This move enhances mutual trust through absolute physical security, demonstrating to Washington and Tehran that the negotiation table is also a safe haven for information and security. Currently, there is no new schedule for US-Iran negotiations.
