Writing in The Diplomat on Feb. 20, R. Nicholas Burns, undersecretary of state in the Bush administration, lamented the fact that India was going to continue to purchase oil from Iran.

He was reacting to reports that to circumvent Western sanctions on Iran's central bank, Delhi was negotiating barter deals (Iranian oil for Indian goods) and/or payment in rupees.

In failing to join in the EU-U.S. sanctions, Burns believes, India has let America down.
