By comparison we don't know how many "zanies willing" to carry out similar attacks to that carried out by McVeigh....what we do know their were ALLOT of sympathizers to his cause. It is a 1 to 1 comparison when you talk about 9/11 to OK City...thankfully many of the usurpers and malcontents of McVeigh's ilk have been interdicted before they could attack.
But here's one reasonably close to your cause...how many Buford Furrows did it take to try and slaughter a preschool full of kids??
Again, these bastards are home grown extremists who pose a far greater danger to the average American the 100K foreign Muslims.
1 to 1 comparison? Hardly. The jihadists hold the roost.
Buford Furrows? You're giving me a random event back by an Aryan doofus in '99 and trying to compare that to the scores of dead and maimed from islamic extremism?
No idiot Aryan or Timothy McVeigh crap could ever dream of reaching the global proportions of islamic terror or the threat it poses to trade,commerce, and regional stability.
Furrows and McVeigh? Come on.
