I'm sure in our lifetime some terrorist is going to set off a nuke or pull a biowarfare attack in a major US city. Our borders are still too wide open. It only took 19 guys to take out the world trade center and hit the pentagon.
Imagine next time 100 suicide terrorists with 10 each going to every major city in the US simultaneously launching shit. The US government and infrasrtucture will collapse instantly and we'll be in total anarchy.
So who do you nuke in retalitation? These fuckers are like rats hidden in the walls. They work in small cells. They have no command and control centers. They live in populated cities and have no military bases to bomb back.
We're sitting ducks and the clock is ticking.
