Not sure if i read Outbound Flight, and some time since reading any of the EU, but impression I had was that Palpatine didn't care about the Vong, just used it as a way of getting Thrawn (who worried a lot about the Vong) on his side, and a convenient excuse for getting rid of a number of Jedi, without making it apparent to Thrawn etc that he was looking to eliminate Jedi.One EU concept that I'm glad Disney has left in the dustbin is the idea that Palpatine did everything out of the goodness of his heart in order to protect the galaxy from the Yuuzhan Vong, whose coming extragalactic invasion he had foreseen through the Force.![]()
