CONFIRM GREEN SKY = giving an order to Captain Green to do something to the Rothschilds.
Q gave us this crumb beforehand, and also wrote a message to LdR (we can hear you breathing).
This was a map. Q told us that future shows the past meaning that a future event (Captain Mike Green doing something with a helicopter to Rothchilds) will explain these keywords and confirm that Q knows top secret information.
Green, obviously a good guy, had a mission. We don't know what exactly he was supposed to do. But it had to be something very serious because bad guys countered very seriously and killed several people.
