Thanks.
I study international relations and diplomacy, so I'm not pulling crackpot conspiracies out of my bum.
Then, with genuine affection, if not respect I would point out your two glaring errors, and why I'm calling you a conspiracy victim.
1. The fallacy that benefiting from an event is enough to tie you to an event.
2. An erroneous assessment of capability.
People see the Western powers benefiting from almost everything, and combine that with a belief that we have almost limitless espionage and military power. The former is true because we're fantastic capitalists and do indeed find a way to get a benefit from most things. The latter is just not true. And even if it were, it presumes that Western governments have a cohesive narrative and goals which the secret powers actuate. But the most cursory study of history should have shown you that we don't work that way. Even during high tide points like the end of WW2 our policies and power was a total muddle.
