Since you clearly can't read nor comprehend what someone wrote I'll break it down for you. The US Militarty could take out the cartels OPERATIONS (aka, the drug fields and where the magic happens to make the coke/heroin/etc.) with the blink of an eye with no US MILITARY CASUALTY'S (aka they could use drones to bomb the crap out of them without a single US human asset in harm's way. No operations, no druggy druggy's being produced. This would drastically impact the cartels.
Now if you go back and read what I wrote, I never once said anything about getting to and arresting the kingpins and their ilk did I?? That of course would be a different type of military engagement. However, this too could be done similar to shutting down the operations but would be at the expense of drastically more innocent casualties and as I am sure the scum bags would hide out in populated areas...and of course we would never do that.
My opinion would be to take out the operations as I indicated, then use financial means to root out the kingpins...aka offer $$ to the poor people and then use our elite military forces to go get them.
