AmericaBlog reports that J Sidney McCain stated that he was concerned about the "Iraq/Pakistan border": http://www.americablog.com/2008/07/mccain-worried-about-situation-on.html
Some commenters have pointed out that Iraq and Pakistan don't actually have a border and assume that J Sidney McCain is just being an ignoramus. Again.
In his defense, there are other explanations:
1. J Sidney was thinking of the future border in the middle of the vast inland sea where Iran will used to be if J Sidney's evil schemes come to pass.
2. J Sidney doesn't know the difference between Iraq and Afghanistan or India or any other country that actually borders on Pakistan, and why would he, God bless him?
3. J Sidney was thinking of Iraq and some entirely different country which it also doesn't border.
4. J Sidney was thinking about two countries other than Iraq and Pakistan which don't have a border with one another, either.
