I was at a private talk discussing the problem of a nuclear armed Iran, and the delicacies surrounding it's prevention.
She explained that Europe was terrified of how America would handle this. Europe looks at America like a Lab puppy in a crowded room: they get an idea that excites them, wagging their tail, obliviously knocking things over and annoying people around them. The enthusiasm makes everyone nervous, as they think decisions should be carefully thought over, and action taken in increments.
Whether true or not, I thought it was pretty funny.
