Nobody has been tough on the Saudi's but you seem to really want Obama to stick it to them on a weapons deal there.
According to the whole of LibBot Nation all of the bad acting, support of Theocrats and support of despots, unilateral regime change etc. etc. Was all going to end under the Obama administration, remember?
Instead, your guy didn't meet one he didn't like and the one's he didn't like, he either installed or tried to install (via regime change by proxy) something or someone even worse.
Context and nuance, still not a resident LibBot Nation strong point.
