We are not talking the middle east here, if that is your reference. It would be cheaper to build the infrastructure in Mexico to handle the poor and displaced civilians. As far as the cartels, complete annihilation, genocide if you will of anyone associated with the cartels. Of course, that would be awkward for many in our government who obviously collude with them.....
I’m talking modern history, not just Iraq or Afghanistan. And, victory in that sense INCLUDES the money to build, tear down and rebuild the infrastructure over and over. We’ve already spent that on the war on drugs and expenses here in the US from the havoc that leaks out from there.
Although your plan is perfectly logical, there are those of the libertarian persuasion who will wring their hands and say that accountants and bank-tellers will be next on the list.
