>> President Trump's decision to reimpose sanctions on Iran is one thing, but getting foreign companies and countries to actually agree to the sanctions and stop buying that oil is another. A small group of diplomats in the State Department has been called to action, but face a more difficult task of getting others on board than it did back in the Obama sanctions from 2012 to 2015, says Reuters Washington Correspondent Timothy Gardner.
>> In 2012, the State Department had a huge advantage. The EU just had placed its own sanctions on Iran. That cut Iran's oil sales down to zero from Iran to the EU and did about half the job already for the US. This time, the EU is not on board.
>> That creates a problem for some of the arm-twisting that needs to be done with Europe opposed to the sanctions. Those who want to buy Iranian oil can do so with money other than the US dollar, removing the watchful eye the US Treasury had on possible sanction cheaters under the original sanctions.
>> Definitely people who used to work at the State Department's Energy Bureau say the current administration doesn't understand what a difficult job this is going to be. First of all, you have to go out into the world and say, basically interfere with other countries' economies saying, you want them to remove steady sources of a supply of oil.
>> And then urged them to buy non-sanctioned oil even if it comes with a higher price, making things harder? The State Department group is also responsible for safeguarding against cheating on the sanctions and is without a leader. At the same time, it already has its hands full with actions with Venezuela, trade spats with China, and upcoming talks with North Korea.
