In an article in The National Interest, Tabler accused the president of "looking the other way" where Iran’s energy assistance to Syria was concerned, “even though Tehran’s shipments are a flagrant violation of both US sanctions and the administration’s stated policy of securing a solution in line with United Nations Security Council Resolution 2254, which calls for a Syrian-led process that would create a permanent, peaceful, and political end to he conflict.”
Tabler suggested that there was “no better place” to start increasing pressure on Syria “than by targeting Iran’s oil shipments to Hezbollah via Syrian ports,” and recommended that Washington slap both the National Iranian Tanker Company and the National Iranian Oil Company with Syria-related restrictions. This, he said, would “send a powerful message to the regime that continued reliance on Iranian energy would come at a cost”.
