He probably should have done, or at least known enough not to trust them further than he could chuck them.
But I think a) he didn't fully understand how deep the hatred of the Allams is for so many, and that's it's beyond repair (this was from talking directly with him), and b) he has been misled (or naive / too trusting, or more likely both) in terms of intent to strengthen in January.
I think he's a good, honest man, and a very decent manager, but I can't for the life of me understand why the hell he would agree to work with the Allams. I know he wanted a job, and he'll be reasonably well paid (all relative of course), but he surely wasn't that desperate to risk having his reputation left in tatters.
