Overview:Tonight, author of No god but God: The Origins, Evolution, and Future of Islam, Reza Aslan. The show begins with "Mess O' Potomac" as Jon talks about the new Iraq spending bill that promises Bush half of the money now and the other half contingent on a July progress report. Of course, Bush plans another veto saying that any restrictions placed on the Iraq War by Congress is unacceptable and promotes defeatism. So when will the war end and what is Bush's definition of victory or success in Iraq? Jon looks at a series of clips showing the flexibility of Bush's definitions over the course of the Iraq War and also talks with Baghdad Bureau Chief Aasif Mandvi. Finally, Jon crosses over the Atlantic to Great Britain, where Tony Blair announced that he is planning on stepping down as Prime Minister on June 27th. Jon goes over some of the highlights of his speech in a segment called "The Blair Ditch Project".
