I agree with much of what he is saying. Regime change is risky, we can't guarantee who will take power and as has been the case in Eygpt and Libya these successors may not necessarily particularly pro western. I'd prefer to stay out of Syrian affairs on the condition military action in civilian areas is scaled back and terrorist cells are not tolerated.
Its selfish but I'd prefer to stand by while a nasty, but benign and malleable dictator rules, than at great cost install a hostile 'democratic state'.
I also think people see the US-Israel relationship incorrectly. The US is using Israel, but as such does need to make some concessions. Israeli intelligence in the area must be invaluable for the CIA. As the US has shown time and time again, it serves only its own interests, its just that currently those dovetail nicely with Israel's.
