We spent our credibility with fake intelligence in Iraq: aluminum tubes, crude fakes on Niger Uranium, Powell's use at the UN of a British report with uncredited material from a grad student found on the Internet, the trailers that were only trailers, and the constantly changing stories on where the WMDs (if any) are (here, there, looted, hidden, just not found in a country the size of California).
Now when we need our credibility on North Korean nukes we don't have any.
Who was it who said the Republicans were better on National Security?
