1. Is that Aleksandr Lukashenko, Pres. of Belarus?
2. Abdullah II, King of Jordan
3. Looks familiar… but also looks like a mugshot :D
4. Tony Blair, PM of Britain
5. Jacques Chirac, Pres. of France
6. Bill Clinton, Pres. of the US
7. Kofi Annan, Sec Gen of the UN
8. Jiang Zemin, Pres. of PRC
9. Vladmir Putin, Pres of Russian Federation
10. Can’t remember but I’ll guess the Pres. of Indonesia.
11. Fidel Castro, Pres. of Cuba
12. Gerhard Schröder, Chancellor of the Fed. Rep. of Germany
13. Edvard Shevardnadze, Pres. of Georgia

20. I know this guy (with the mustache) but I just can’t remember. Pres of Argentina?

22. Another one whose face I recognize but can’t quite remember. I was thinking Mahmud Abbas, but two Palestinians in the same shot? Can’t be right.
23. Réné Préval, Pres of Haiti. Embarrassing I only got him on a 2nd/3rd look, because I actually met him in 2001.
24. Hugo Chávez, Pres of Venezuela
