Govindraj, go and read quran, it says exactly what they want.
What they want is to make the whole world islamic and ruled by sharia. Thats all ISLAm stands for, and then you get peace according to ISLAM. Thats why they say ISLAM is peace.
Go read the quran, at least if you consider terrorist are your enemies, know your enemeies. And all terrorist flash their quran at your face. Its so illogical that non muslims dont read quran.
