The first thing I need to know, and that too because I consider myself an amateur, is that was any religion ever spread (and here I refer to not the ideology but the system the religion imparts) by other than the sword? Jews gained land by fighting. Hinuds gained land by fighting. Muslims gained land by fighting. Christians (Catholic) gained land by fighting. Now let's assume for one minute that no religion is right but are after power. What other options do we have. Science. Well, doesn't every power extend by force. Isn't America currently spreading democracy by force? I for one do not want democracy. I prefer Confucianism. Who gives America the right to impose democracy on me? Just because they think it is right does not give them the right does it? Now every ideology when in power tries to expand its empire and history bears witness to this. Look at the British empire. Look at the Ottomon empire. Look at America. Some do it with outright force while others use hidden tactical methods such first making a country dependant on them and then imposing sanctions to get their want. So what is the solution. Should we all agree to the land maps we have and everyone should have the right to impose whatever law they want in their land without external intervention? Or is it human nature to want to expand and since it has been happening since the dawn of time we will continue fighting?
