so the CIA can blame it on the Iranians. If they're Iranian made, they blame Iran.
Same reason, the USA bought every AK47 they could get their hands on and smuggled them into Afghanistan during the Russian conflict.

This is a double edge sword, $$$ does amazing things. I know if I was a multi-billionaire, I'd let it be known that I have a 1 billion dollar contract out on whoever is responsible for killing me. I'm sure a 100 million would go a long way. Hell, Saddam H was getting people to blow themselves up for 20k cash.
