Hank,
That's was my point. If you can't secure the borders, I doubt very much  that 
you can win the war. We created a vacuum and the insurgents are filling it  
and will continue until the "coalition" has finally had enough and leave. 
In spite of the vast expanse of borders, we certainly have the technology  to 
detect infiltrators and stop them before they could get very far into the  
country. I suppose you then run into the problem of native tribesman who  
normally use those routes to get around and do business. Probably a few camels  
would get killed, but less of a loss than human life.
I'm also sure that the insurgents use specific routes to enter the country,  
using safe houses and places where supplies are stored for them. You never 
hear  about these places being found on the news. When the war first started, the 
 border crossings along major highways should have been sealed and they 
weren't.  Most of Sadaam's henchmen made it to Jordan and Syria crossing the 
borders  in private vehicles. Just my personal views on tactics based on a years  
experience in Vietnam and six years of military/tactical training.
