The fact he was 40 points in the lead in a car slower than the Red Bull, McLaren and Lotus is the incredible part. You can try and rewrite history as much as you want but people can still watch the old races and see the real evidence first hand. He lost the title because of Grosjean crashing in to him at Spa. i.e it was not his fault.
That is what makes 2012 one of the best seasons by a driver ever. Much better than Vettels titles in dominant cars or Hamilton winning because he's driving a supercar against someone like Rosberg.
Still, keep on making things up, it' like the monkey theorem, hitting random keys on a typrewrite, I'm sure after another 1000 posts you will write something that is a fact with context.
Alonso lost the championship because of Spa? Utter nonsense - if Vettel's car hadn't broken down from the lead in Valencia, the events of Spa would have made little difference. There's no doubt he drove a fantastic season in 2012, but his position was largely due to factors external to Ferrari.
We could also talk of Hamilton's reliability - dropping out of the lead of three races, retiring from the German GP where he would have likely scored a very good haul of points, and suffering an anti-roll bar failure in Korea while up at the sharp end, without which would have almost certainly moved Alonso to 3rd in the championship. The point being - what-ifs are not facts.
