Given his third-place finish Hamilton needed Vettel to finish seventh or lower to secure the title. Too many question marks on how some races or championships were won.
"I think the respect between us has always been there despite the fact that maybe we are very different".
Gasly said: "It's quite a harsh penalty, if you've been really careful when you pass in front of the crash and just after you don't pay attention so much and you get a penalty like this". Hamilton has 71 victories going into Sunday's race at the Circuit of the Americas.
Just seven races ago, Hamilton was eight points adrift of Vettel in the standings and Mercedes was struggling to match Ferrari for pace, but he now holds a commanding 67-point lead with four races to go.
He roared past Ricciardo on the back straight, only to go too deep on his brakes, and lose the position.
Surprisingly, the 1997 world champion admitted that Schumacher wouldn't even make his top-five list of all-time F1 greats on which he puts Ayrton Senna, Alain Prost, Niki Lauda, Jackie Stewart and Hamilton.
In a desperate attempt to get back past at the right-handed turn 13, he collided with the Australian and spun round in a plume of tyre smoke, dropping to 15th.
At first, it looked as though it may have been an inspired decision, but it backfired when Hamilton's rubber ran out of life and he had to stop again.
Raikkonen dropped to fifth behind Vettel, who was yet to pit - they would shortly switch places, allowing Raikkonen to maximize his fresher rubber - and both were promoted to second and third once Bottas and Verstappen made their tire changes, with Valtteri losing a place to the Dutchman in the stops.
Raikkonen, who turned 39 last Wednesday, becomes the sport's eldest victor since Nigel Mansell in 1994.
'Firstly a big congratulations to Kimi, he did a great job today.
"After two or three laps there is basically no lap time difference between the compounds and maybe after five laps we can start to have the edge".
Vettel will have to outscore him by 21 points - in other words, win the race with Lewis failing to finish - to keep the fight alive beyond next weekend's Mexican Grand Prix.
