Who Knew About the Plot To Bomb the Russian Plane and Did Not Alert the Russians

Here is what I think happened not too long before the Russian plane blew to fucking pieces high above Egypt.

British, American and perhaps other western intelligence agencies got wind of the bomb plot. They communicated with one another about what they knew. Someone probably asked someone else, "Should we tell our [political] leaders about this?" It was then agreed that because their leaders are a bunch of fucking buzz kills it would be better to keep them in the dark - permanently.

Why? To teach Putin a lesson.

I await Putin's response. I am fairly certain he can smell this rat without my help.
