Just exactly what crop would you suggest an illiterate farmer plant that will be worth a few $1000 per kilo? The answer to your question is NO!
That being said, the solution to the problem is to make the crop worth a lot less than it is right now. Legalize, decriminalize, whatever name you want to give it drugs. The price will drop, cutting the current crop of sleazebags off at the knees.
Drug enforcement agents can be immediately re-deployed to fight terrorists.
With the drug dealers' enormous profits gone they will promptly become just commonplace ordinary criminals unable to bribe anyone.
..... and will go back to being great fat tubs of lard, border patrol men, police chiefs and sherrifs' deputies and the like -- just like before the only drug crime, ever: PROHIBITION; was perpetrated!
People on the ground there say we are dropping about 1/2 of the agent orange on areas that grow little or no coca. Just an effort to move the indigenous tribes out of the oil companies way.
