If it is not about congratulating, did they tell these soldiers even once that it is wrong and hypocritical to go to Afghanistan and that your war is not legimate and rather unmoral? So that means if you invite a bunch of killers and rapists to the mosques, knowing fully well they are going to kill your brothers next day, you are going to "invite" them to Islam or "tell" them about it, without even once hinting to the heinous deeds they are about the commit? What kind of nonsense is this?
