The implication is that Sarko is a parvenu, a noisy outsider trying to get in, and a bit of a spiv.

All of which is true. Although if he'd followed the neo-con line more faithfully I'm sure he'd have been hailed as magisterial, effortlessly dominant, a born leader, and all the rest of the usual rubbish.

So the undertone of contemptuous disapproval is there for spiteful reasons. He's not quite a neo-con creature, and this is telling him that because of that resistance he's never going to be the insider he wants to be.
