It's just realpolitik laid particularly bare. The major complaint seems to be that the paperwork wasn't done 'right' here, not much else eh?

What is the real difference between Iraq and what just happened, except this was arguably done much cleaner, and with less BS (no having to come up with Yellow Cake, or fake WMDs, for example).

This does have the effect of hopefully waking up anyone who is still confused, but I doubt it.
