So if I'm correct, you're taking the realist tack, in that Canada will benefit economically while somehow having hundreds of modern LAVs will cause the Saudi government to fall more quickly. This last point is presposterous. The LAVs will be replacing older LAVs in the National Guard, which is the force that would be used in to crush any protests or open opposition. In the long run, arming a despotic regime in Saudi Arabia only guarantees that whoever replaces the royal family will be further radicalized and be immediately hostile to Canada. The classic "they already hate us argument" is also problematic because it assumes these people are not rational actors at all, and are somehow a homogenous group. IF we are at all concerned with protecting Canada ( I don't believe there is much of a serious threat, and if there were, our government's policies are not going to be effective in meeting that threat), we need to be looking at diplomacy, not selling weapons abroad.
