This is typical "open mouth insert foot" syndrome. Biden wanting to brag about his international history knowledge wind up criticizing his own running mate.

I think whoever wins has will be tested:
1) Weak economy, global recession, massive deficit and future inflation.
2) Old infrastructure
3) Energy security and independence
4) Global warming
5) International threats (terrorism, Russian resurgence, Iran, N. Korea, and Iraq)

Pretty tough list of challenging issues.
