My knowledge of rockets and the like does not extend beyond the M-79 but one thing I do know is any such weapon is fungible. We give it to say Egypt, it can move on to say Yemen, Syria, Angola or the US.
I see where Bush is having Heart surgury today. I wonder if his open minded immigration policy extends to having a doctor trained in Mexico. Just a though.
There are plenty of ways to modify the $58,000 bottle rocket to make it do some serious damage to a building, but it is probably best to not give them any ideas.
