No syrian judge would be able to do that until they too signed up.To sum up. The day an American soldier stands accused and tried by a Syrian judge for human rights violations is the day the day that Damasus is either a smoking hole in the ground or the site of a Disney Theme Park.
Which they of course would not dare since they are afraid that USA would indice their soldiers. It seems to me that the only nations not signing up are the nations that are afraid their soldiers might get into a "situation". We all know the list of those countries. Interesting that the brits and french etc are not so scared of syrian judges.
