Why do they lose? Because 72 virgins isn't much of an incentive to fight or commit acts of terrorism when your religion prohibits your women from bathing.

Please, let's not oversimplify.
These killers are real and there are too many of them; and yes, they are still mainly killers.

They kill, burn, rape, pillage and loot mainly for the virgins they get here and now.
That hasn't changed. 20% of the loot is due to their god (through the Caliph), the other 80% is distributed among the invading army.
This is still central to the spread of Islam.
