I totally and fully support Turkey hosting the 2020 Olympics.
Turkey is the most functioning, stable, and vibrant country with a Muslim majority. This is the country that Pakistan should have been had we listened to our founder Jinnah.
Turks are great people, with a great sense of history, pride and nationalism.
I have been to Turkey many times and I have always been touched by the hospitality they have shown me.
Istanbul will be an ideal candidate to host the 2020 Olympics.
Spain is going through a tough economic times and it will be e mere 8 years since London hosted the 2012 Olympics so I doubt they would want to bring the Olympics back to Europe with Madrid hosting them.
Tokyo, Japan is the same. They had a devastating earthquake and tsunami so they might get sympathy votes but it will be a mere 12 years since Asia hosted the Olympics last in Beijing and I doubt they would want to bring them back to Asia so soon.
All signs point to Istanbul, Turkey. Istanbul Olympics will touch upon themes of Islam, History, East and West, and looking towards the future.
Also, with Istanbul hosting the Olympics, 2024 Olympics will definately come back to North America, and hopefully Toronto hosting them.
The only negatives about Turkey would be the Security situation and the horrendous Traffic in Istanbul.
