Today’s debate comes as major splits continue to emerge within both parties over the war. On Tuesday, Massachusetts Senator John Kerry told a gathering of liberal voters at the “Take Back America” conference in Washington that the Iraq war was a mistake and he was wrong to vote for it. Kerry announced he is introducing a resolution for a withdrawal of troops by the end of the year. Kerry attacked the war’s architects as “armchair warriors whose front line is an air-conditioned conference room.” In an interview with the Boston Globe, Kerry later added: “It is both a right and an obligation for Americans to… end a war in Iraq that weakens the nation each and every day we are in it.” Kerry’s proposal would keep some troops in Iraq to train Iraqi soldiers.
