The U.S. is getting ready to draw a line in the sand when it comes to Iran. The U.S. plans to economically isolate Iran from the rest of the world by 2010 if Tehran does not agree to allow international inspectors to examine its nuclear program, according to The Washington Post. The Obama administration’s plan, led by Treasury Under Secretary Stuart Levey, would include establishing new sanctions as well as intensifying already-existing ones, and would focus on insurance and reinsurance companies, which are key for international shipping. The plan is at least in part in response to two days of missile tests in Iran last week. "Towards the end of the year, we'll be able to calculate how much progress [has been made]. … If they continue to fail to answer the questions, then obviously there will be implications and consequences to that, as well,” said State Department spokesman P.J. Crowley.
