Consider the Twin Towers Attacks (which indirectly enriched the Saudi Royal family immensely).

Osama Bin Laden has been exiled from Saudi Arabia in the 1990s and had his citizenship revoked 7 years before September 2001. The US chose to ignore intelligence about an imminent attack and was also working with Al-Qaeda in East Turkmenistan. The people who profited from the attacks were US companies' CEOs and shareholders.
