A Modern Crusade

 I think it would be failed,all Crusades were fail except the First Crusade, but there is a propblem we don't have Baybers, I call him (CRUSADER SLAYER) he defeated Three crusades.

you put Israel in your topic to play a a big part as a ally I must disagree with you cause if it would be a real Crusade any helping from Jews will be refused.

when the Crusaders entered Jerusalem they murdered almost every inhabitant of Jerusalem. Muslims, Jews, and even eastern Christians were all massacred.

Have we all forgot what the Islamic group Al-Qaeda has done in NY?

I dont see this as religous, its a matter of freedom and protecting a countries citizens. Ask yourself, if the US were to have sat back and did nothing after 9/11 how fast would have the disease we call Islamic fundamentalism have spread? 

Medieval armies of all nations and faiths slaughtered and abused the civilian population of cities that were conquered.  You are judging the crusaders by todays standards rather than the standards of the time.  You may say that no one was forcibly converted to islam, but even if they didn't they still made life miserable if you were not a muslim.  Everyone else in a medieval islamic nation was considered second class.  That and that fact that they converted churchs into mosques left few places of worship left for non muslims.

They are even cruel for their own times, you can ask this to greeks, first, second or third crusaders, every one of them harmed byzantium one way or other.
