And Michael Flynn?
> do things against the wishes of the Pentagon
I'm betting that the Pentagon prefers their retired senior staff don't whore themselves out to potential adversaries. But unless and until they cross a formal line, what are you gonna do? If the Pentagon comes across as punitive, e.g. by revoking any latent security clearances, there'll be a huge backlash. This form of consulting and liaising with international groups by retired military is nothing new, and there are legions of retired staff leveraging their status one way or another. It's a perk of the job. It's also not new that it can sometimes be rather unseemly, to say the least. What might be new is the amount of money being thrown around.
These relationships are quite valuable because while it may not seem that way in our social media bubbles and among our international cosmopolitan peers, the day-to-day cultures and administrative machinations of various governments and militaries can be extremely opaque simply because of the huge differences in presumptions and expectations. And this is true even among allies with seemingly similar cultures, which is why even a country like the U.S. with veritable armies of intelligence analysts do ridiculous *hit like bug Angela Merkel's cellphone. Retired personnel don't need to divulge secrets to provide extremely valuable and timely insights, especially as between countries like the U.S. and Saudi Arabia.
