A Thousand Lives

I heard the news today, oh boy. A thousand US troops have now died in the "liberation" of Iraq since the fighting began in March of 2003. Dick Cheney threatened the US with another terrorist attack if George W. Bush loses the November election. And Kerry is being branded a flip-flopper for voting against Bush's $87 billion request for the funding of the continuation of the Iraq War.
Forgive me for interceding, and for injecting my own opinion, but didn't George Bush try to convince us that the war would cost something on the order of $20 billion back when he was talking all of us into it? Why isn't it Bush who is being accused of the flip-flop?
