I'm sure most Germans, Russians and Chinese didn't (or don't) share the opinions and goals of the Nazi and Communist Parties. They still did the dirty work, paid the taxes, obeyed the orders, etc., that allowed those monstrosities to kill millions upon millions.
I wonder how much money your patriotic Muslim coach send to Muslim "charities" that fund terrorsists like Hamas, Hezbollah, etc.?
The combatants we are fighting in Iraq--- and the murderers who beheaded these four innocent girls --- do not represent nations. Whatever responsibility citizens may have for what their nations do, the 1 b Muslims in the world --- many of whom are victims of Islamic terrorists --- are not responsible individually or as a group for what stateless terrorists do.
In any case: deliberately or indiscriminately targeting non-combatants of any nation (including WWII-era Germany and Japan) is still a violation of International Law, United States law, US Code of Military Justice law, and God's law.
It is damnable.
Anyone who in fact sends money to terrorist organizations, should be prosecuted to the fullest extent of the law. If I were on the jury I would yell "Guilty!" and if I were judge I would impose the maximum penalty.
But I very much doubt that you know anything about Coach Sabri in particular. And in America, we only accuse, investigate, arrest, and prosecute people in particular. Or do you propose that we incriminate my Tennessee neighbor on the basis of his name?
For shame.
