Is it time for full-body scans for international flights?

Does the Christmas Day terrorism attempt dictate that it is time for international flights bound for the U.S. to use full-body scanning devices? Should air travel in general require more security measures? Or was the Christmas Day attempt not serious enough to warrant wholesale changes in security? Are there more simple, sensible changes that can be made?Should “watch lists” play a larger role in who can board a plane?
