I'm afraid our culture has been diluted to the point where presenting a strong united front on ANYTHING is forever a thing of the past. As far as I can tell, from a historical standpoint, no country, empire, etc., has ever reached the equivilant to where we are in our life-cycle and subsequently recovered from it to regain the qualities that propelled it to greatness in the first place.
Hit the root cause and problem squarely on the head.
