"I think that experience is very important for dealing with the world as it is today."
Perhaps. But, you know who had a LOT of experience in 2000: *** Cheney. And Donald Rumsfeld. And Paul Wolfowitz. All those guys had been in the foreign policy apparatus for thirty years or so. So, pointing to experience as somehow important, or a deciding factor by itself, doesn't really cut it.
The counter argument is that the guy at the top, George Bush, didn't have experience and that this led him to be more easily swayed by those that did. I'm not sure that really cuts it though. I think that has more to do with the personalities involved than anything called experience [either a lack thereof or an overabundance].
Ultimately, it must be the person's ideas and understanding of the issues that carry the day, not the years spent in the bureaucracy. Indeed, it could probably be argued that someone with a lack of experience in the Washington sense, i.e. many years spent milling about DC, is better qualified than someone with that experience because they do not have as much group think baggage as those who do; they may be more representative of the actual will of the people.
