I’m not sure how much the kingdom was involved in Al Qaeda’s early years, unless you count American-Saudi-British funding of MAK/other Mujahideen during the soviet-afghan war. However, it’s clear Al Qaeda was already declaring against the kingdom a couple years before the USS Cole in '98. But sure I’d see Al Qaeda being a child of SA in a way similar to the KKK being a child of the US
That’s what we expected when Biden won in 2020, then Jan 6 happened and Trump is running again. There’s an implication that things will gradually return to some 2007/2008 status quo (which was also very polarized) and right-wing extremism will simmer down. But there’s no reason for it, no cultural forces for it. Right now there’s no reason to think another Trump or someone worse won’t take up the mantle of owning the libs by grifting the right.
