The US at one point banned the resale or ownership of surplus fighters, I think there are a few A-4's, A-6's and maybe even a viper or hornet that got out of the barn before the law was passed, but no more.
This guy bought the harrier from the OK, so the US law doesn't apply apparently. But he couldn't buy or own a surplus US harrier today.
