.0000001% it could be true but what if it was the long con. From a Reddit user:
If you think about it, the US played a perfect end game. They knew Saudi Arabia was responsible for 9/11, but played along since taking Mecca would have united the entire Middle East and started a huge regional war. So the US started to chip away at every 'Cold War'-armed ME nation with direct invasions (Afghanistan, Iraq), revolutions (Arab Spring, Syria), and sanctions (Iran) until none were left standing.
Last year, the US 'made a deal' with Iran to lift sanctions in exchange for non-interference in future conflicts (Iran reduced forces in Syria as an act of good faith). Saudi Arabia knew its time was running out so they put their Wahhabi terrorism project (ISIS) into overdrive to delay/deter US intervention.
This is near the end for the Kingdom of Saudi Arabia. The US has started to use its most powerful tool, the mass media, to rally their people and inform them of the true enemy. Economic withdrawal or military intervention will result, and the Kingdom will fall. There will be more terrorist attacks as this process continues, but we must hold steadfast and let justice be done.
Revenge is a dish best served cold.
Any conspiracy theory that requires more than three levels of geopolitical competency is creamy bullshit.
