The U.S. Treasury Department’s point man for sanctions and terrorist financing said Monday, November 12 that the Obama Administration has no plans to weaken economic sanctions against Iran until it addresses U.S. concerns about its nuclear program, The Wall Street Journal reported. David Cohen, undersecretary for terrorism and financial intelligence, said the sanctions, along with “the Iranian government’s own gross mismanagement of its economy,” were having a major impact, and warned the pressure would continue. Speaking at a conference in Washington, D.C., Cohen added that the range, depth and power of the sanctions against Iran “are unlike anything any country has ever encountered.” Iran’s petroleum exports, the country’s most important source of foreign exchange earnings, have declined approximately 55 percent this year, Cohen said, and its currency, the rial, has lost approximately 80 percent of its value against the dollar over the last year.
