The author of that blog entry is calling bullshit on the Russians claim.
I would too. The Russians have always talked bullshit about their abilities.
Even now the Russians know they wouldn't stand a chance against the US in a conventional war. We have several divisions of battle hardened Soldiers and Marines. The Air Force would whip the shit out of them in hours. Navy wise..... well the Russians don't really want to think about it...
The ONLY reason they have been able to pull off what they did in Georgia is because we are spread think in Iraq and Afghanistan. Even then we "COULD" kill off their air superiority at any time. Russia is banking on the fact that Bush doesn't want to get into a fight with them and the fact that the other NATO allies are pussies.
I think the Georgian President said it right when he stated that NATO's failure to allow them to join basically invited the Russians to invade. But then it is looking like Georgia MIGHT have started this whole shebang to begin with...
Iran is more of a threat to its neighbors then the US, they are not an economic power so they wouldnt have the resources to fight a war with a super power, all they could really ever do is drive the price of oil up with a mid east war.
China on the other hand is a super power, in 3 years they will have the worlds largest nuclear submarine fleet.
