Zubrin argues from a very simple perspective?
"Take away the money and the large-scale terrorism stops because they can't afford the equipment to blow shit up. It's really that simple. But I suppose that makes me a bigot..."
No, but it does suggest you are poorly informed. If you look a little wider into terrorism - including virtually all the bombs within the US, you'll find no international sponsor.
BTW, Stating the fact that Saudi Arabia is the source of many terrorism dollars is not bigotry, it's simple honesty; the evidence, for those who choose to look, has been widely available for many years.
But saying that fact is not the same thing as using that info to launch an anti-Muslim broadside. THAT's bigotry. And that's what he's doing.
Bush-ites are scared to confront Saudi (as is the Brit government); fomenting against ALL Muslims is a cowardly and stupid workaround. If this guy REALLY cared about the issues he claims to care about, he'd be arguing that bombing Saudi Arabia would be much more effective than bombing Iran; both routes are pretty bloody stupid, but if you want to bomb, as the RAF used to say, pick the right target. But bigotry is cheaper, I guess.
I find it sad the the 'war on terrorism' [sic] seems to have just two fronts; fostering anti-Muslim sentiment and demonising Cuba, neither of which is likely (in my oh so humble opinion) to achieve peace. Or anything else.
