I think, Doha's bid is the best.

- The logo was created by synergy of art students from different nationalities!

- The slogan is in the perfect timing

- The cause reflects right the target of Olympics - humanity

- Core purpose to unite by peaceful ways is unmistakeably strong

- Proven successful host of international sporting events is a foundation

- The cause to spearhead the special sporting event & facility for the physically-challenged people is just as another big PLUS

- The idea behind knowing where u r (geographically & economically), what uv been (clear past & history), and aspirations (future goals and amibtions) is just very striking
