If Kerry's statement is unanswered by Bush, the MSM will make Kerry look like a hero. I would expect Bush to say that Kerry is free to criticize his prosecution of the war on terror, but he should not resort to demeaning our men and women in uniform -- ever! He owes them an apology, period.
The last time someone openly defied our president like this was when Chavez spoke at the UN. Bush has to answer.
