I agree that Raheel Shareef is frustrated ,he tooka decision only in his favour to retire respectfully .Coming to the extension no Genral can extend himself ,it is Prime minister take a step ,to see another senior to replace him .iIf he tries to supercede the senior and try bring his own chummy ,he will face a wrath ,then the world is watching that no General comes in Pakistan who is belligerant and can derail the democracy ,or he can show some independence in his character ,the Govt of Pakistan is run by defecto rulers in Army ,and so called democratic elected govts but Army plays the game .They decide if intelligent General comes heading where the policies are moving if they see threat to the basic idalogy of the country they come rescue it .Being nuclear power world will always keep Pakistan leaders and Army Generals on RADAR.
