There's been so much hoopla surrounding the Republican primaries, what with debates and caucuses and attack ads and Super PACs, that it's easy to forget there's a great big world out there. On tonight's Daily Show, Jon Stewart checked in on Iran and the latest news on their uranium enrichment program. They claim it is for research purposes, the United States doesn't agree, and then there's that all that nasty business about blockading the Straight of Hormuz and sentencing Iranian-Americans to death for spying. It's like living in a sweeping epic that probably won't have a Hollywood ending.
