So apparently the Saudi royals are taking their queue from Donald Trump in going nuclear whenever anyone tweets something they don't like. In response to a tweet from Canada about a womens rights campaigner (the sister in law of people Canada has accepted as refugees and given citizenship to) the Saudis have withdrawn their ambassador, expelled Canada's ambassador, ended all future trade (except for selling us oil, of course), and ordered 12,000 Saudis studying in Canada to end their studies and go elsewhere.

It is, I think, worthwhile pointing out that while assorted progressive idiots insist on blaming western interference in the Arab world for terrorism, almost every world terrorist group subscribes to the Saudi Wahabbi form of Islam, which is extremely violent, intolerant, and hateful towards anyone not following that school, but particularly to Jews and Christians. ISIS and Al Quaeda are both inspired by Wahabbi Islam, as are other world terrorist groups like Al Shabaab and Boko Haram in Africa, as well as Indonesian terrorist groups. Their common religious ideological beliefs flow through Saudi Arabia's cult-like version of Islam, which it has spent many tens of billions of dollars spreading around the world.
