So anyway, getting back to the point...

Saudi Arabia didn't invade Bahrain. And how do we know that? Because the USA said it didn't.

So either we believe the big nasty evil USA, in which case Saudi was doing the Bahrainis a favor by popping in for a visit, or we assume, as usual, that the USA is evil and can't be trusted and everything they say is wrong, in which case Saudi Arabia did invade Bahrain.
