But to answer your question;
I would also put bone cancer causing chemicals in the municipal water supply. And tell them it's good for their teeth.
I would open up thousands of little overpriced corner stores and gas stations that sell lots of processed foods full of harmful chemicals that cause all kinds of health problems and laugh my ass off while the stupid fools consumed them.
I would set forth an entire network of operatives to infiltrate the medical and psychology industries so that once they are sick, with the help of the poison already being produced by the pharmaceutical companies which I would hold stock in, cure is impossible. Treatment will further sicken them and my cause will be funded by their slow demise.
Simultaneously, I would form activist groups of moles. They would receive government grants to attend American law schools so that they could use the US Constitution against the US, in the guise of equal rights.
HELL THATS A LOT OF WORK WHY N IOT JUST DUMP POISEN IN ONE OF THE UNGUARDED GRAIN SILOS THAT ARE ALL OVER THE COUNTRY. A LIITTLE RICEN GOES A LONG WAYS FROM WHAT I HAVE HEARD ON THE NEWS. THIS COUNTRY IS WAY TO VUNERABLE BUT AT THE SAME TIME WE DONT WANT HOMELAND SECURITY UP OUR ASSES EITHER. ITS A TOUGH CALL ON HOW FAR WE GO TO PROTECT AGAINST EVERY THING.I would secretly fund the gay and lesbian movements to further decay the value system of a nation who claimed to be formed on moral and Godly values.
I would use the governments police agencies and spy agencies to help create patsies for failed terror attempts. You see, it's the religious and Biblical principles on which freedom and liberty are built upon. A proper jihad operator will have great satifaction in watching a police state form around a once free society, based solely in reaction to his 'failed attemps'.
I would dominate the media and spew my propaganda 24/7 and the idiots would buy every second of it while their children and grandmothers are being irradiated at the checkpoints.
Hell Bellson if I were jihadi camel jockey, I might even be able to put one of my operators in to the position of the presidency.
