My read is, it was a double objective operation. They were going to take out Trump and at the same time give the new administration excuse to start a war since the missile would have been traced back to NK.

The alert was real because the missile was real. They needed a cover and Laura must have been asked to take the fall.

In this post (and next) Q clearly mentions missile is real and was intercepted by F-16 using classified weapons package. He also hints that Potus AF1 was in the sky around there and had to be rerouted.

Potus was coming back from NK with Kim agreeing to shut down the nuclear program. So Cabal wanted to make this an ironic kill. Trump negotiates peace with NK and Trump gets nuked by NK.

In post 2350 he drops the clue that the "The Hunt" was dropped from the "Hunt fo Red October" signature because it was hunted down after the missile was fired. We assumed that the missile came from the rogue submarine and they were able to use it to trace the origin.

In post 4724 Q reiterates that since Trump as an outsider brought peace with NK they tried to terminate him
