Military pilots have relatively few flight hours and they fly nukes around.

Granted, some regionals have better training than others, but in the end its about quality more than quantity of experience. And basically I think alot comes down to each person individually- maybe thats a product of culture at each airline to promote excellence.

In any case, there's a captain there to make the tough decisions, the FO only really needs to be able to fly the plane and thats what the training teaches. Eventually with enough exposure the low-time FOs will learn how to think like a captain.
