President Trump on Friday kept alive the Iran nuclear deal he detests by waiving sanctions for the third time, but said he will not repeat the reprieve unless the agreement is amended to permanently block a potential pathway to build nuclear weapons. Simultaneously with the announcement of the waived sanctions, the Treasury announced a set of new sanctions, some of which are a response to crackdowns on anti-government protests in which access to social media was blocked. The new designations include Iran’s Supreme Council of Cyberspace and its subsidiary, the National Cyberspace Center, which police the Internet, restricting access to various websites that challenge the regime as well as the proxies and virtual private networks many Iranians rely on to get around the controls.
