While it is true that Shrub the First was UN ambassador, I think the more relevant position to Shrub the Second's presidency will turn out to be Papa Shrub's stint as Director of the CIA.

Baby Shrub's presidency has a lot of eerie echoes and long shadows cast by Papa Shrub's past.

I'm betting the reason why George Tenet hasn't been fired by the Baby Shrub is because he has some serious Hooveresque goods on the Shrub dynasty and it's Mayberry Machiavellians.
