Who are they, the USA, oficially, is it not a Christian country? what is the religion of its leaders? I do not refer to the army itsef, the leaders of the country send their soldiers to fight for what they believe it is wrong. The soldiers do their job, same like a doctor istreating a patient, or a teacher is teaching children. I think the US politicians refer to God quite often, they say something like 'God save America' or whatsoever, i am not sure... and naturally, they represent their religion, same as muslims represent Islam. The 'problem; here isthat muslims' faith is stronger than that of the christians, so they use the name of Allah more often than the christians use the name of Jesus. In religion itself, there is nothing to be fixed.
another question. Muslims have a strong sense of brotherhood. If you've noticed, in this forum and elsewhere, people call one another brothers and sisters. That is because we, people, believe, that our religion unites us. So immagine someone would be killing your real brother, would you be standing still then? Or would you try to save him or do sm kind of revenge to the murderer? answer yourself, and you will get the answer why muslims fight back.
