I really do not know how we should proceed, but I believe the elder Bush will counsel, what else, "prudence." Wouldn't be prudent to do otherwise.
He has no problem with getting differing opinions and then deciding on the way he wants to go - that is the way he set his administration up.
He also will be under no pressure to act before they are ready to act. In fact, I expect him to string Bin Laden along. Nothing worse than waiting knowing something is coming.
