For years Iran has threatened that if it were no longer able to export oil because of U.S. sanctions, then no one else would be able to either. The Sept. 14 attacks on Saudi Arabian Oil Co.'s Abqaiq and Khurais oil processing complexes and two earlier attacks on the Saudi oil sector gave life to longstanding fears of Iranian attacks on Saudi critical infrastructure. Iran has clearly made the strategic decision to escalate its attacks against oil industry targets in the region in response to U.S. sanctions pressure and Washington's departure from the Iranian nuclear deal, known as the Joint Comprehensive Plan of Action. The attacks on Abqaiq and Khurais have fundamentally altered Saudi Arabia's threat perception regarding Iran.
