I'd say the War on Terror has a lot in common with the War on Drugs. Neither have concrete achievable goals, neither has a well defined "enemy" and both tap into deep-seated fears of the voting public.

Those characteristics make them great vehicles for political manoeuvring and expansion of government spending and powers. And this is why I think neither will ever end; I could not see any politician willingly throwing away such a tool. I mean, look at the War on Drugs... we've been "fighting" for over 40 years and are no closer to an end.

Look at what we've lost already to the War on Terror, then try to imagine what we will have given up 30 years from now.
