Here's an interesting document about US Sanctioned oil tankers from Iran. It's posted on the US Treasury Department web site.
It states that "Today, the Department of the Treasury’s Office of Foreign Assets Control (OFAC) sanctioned more than a dozen entities and vessels for their involvement in the shipment of Iranian crude oil and liquid petroleum gas to Syria and East Asia on behalf of the Islamic Revolutionary Guard Corps-Qods Force (IRGC-QF) and Hizballah."
“Iran continues to rely heavily on the illicit sale of oil and liquid petroleum gas by the IRGC-QF and Lebanese Hizballah to fund its terrorist proxies and destabilizing activities,” said Acting Under Secretary of the Treasury for Terrorism and Financial Intelligence Bradley T. Smith. “Treasury remains committed to disrupting the networks of shippers, brokers, and buyers that facilitate these schemes.”
OK I know I'm not the sharpest knife in the drawer, but exactly what is the illicit sale of oil and liquid petroleum gas? Iran sells oil to Syria and some how that's illicit. This brings us right back to the rival pipeline war in Syria and the recent coup.
The date of the Treasury notice of the sanctioned oil tankers was September 25th 2024. The date of the Assad coup in Syria was December 8th 2024. So the Americans said Iran was not allowed to sell oil to Syria only Saudi Arabia was.
Again it brings us back to the rival pipelines in Syria. One from Iran the other from Qatar. The CIA created ISIS in Syria to justify American troops opposing the Assad regime and the rival pipelines from Iran in support of the pipeline from Qatar.
Right before Trump was elected in his second term the CIA launched a coup in Syria against Assad and installed their new Al Qaeda puppet president. That crushed the plans for a rival pipeline and secured the Saudi monopoly.
So when Iran sells oil to Syria, that's a terrorist act but when Saudi sells oil to Syria that's good business. Now I get it.
