I think we need to remember that we he says something, we're not supposed to take it literally.
So when we hear it, we must remember that it can be:
1. True
2. Slightly true
3. Partially true
4. True under all the ridiculous hyperbole
5. True sometimes, depending
6. True in a reality TV show way of being true
7. True if certain conditions are met in the future
8. True, in his mind, at that precise moment, until someone changes it when asked at a press conference
9. Fantasy, like he's playing a video game
10. A complete lie, consciously made up from the beginning
11. Really, badly wrong
And all subject to change later, maybe.
