Don’t worry. There’ll be an “oil for food” program, and that’ll allow just enough oil to keep Iran’s pore hungry wee ‘uns eating a balanced, nutritional diet of centrifuges and isotopes.
If they could swing that then another oil for food program will provide endless voucher-bribes for both the media and the politicians from lowly congresscritters on up to lofty UN officials... just like it did last time.
Well, I ain’t exactly worried about the welfare of Iran during sanctions. :)
Not too sure that China will buy Iranian oil during sanctions. They are after brownie points to deflect the usual criticism of them over N Korea, Taiwan and Tibet, as well as basically needing to support US policy in this case. If they don’t they probably won’t get paid.
