Truly religious war? What do you mean? Arabs, Jews, Muslims, Palestinians, Irish Catholics and Protestants. What other reason than religion is there for these people to pick a fight with each other? Are you saying that every war in the last 200 years has no religious context at all?
Try this report from the Far East just two weeks ago:-
July 15, 2008: Despite improved security, the government extended emergency rule for the Moslem south for another three months. These rules, which suspend many legal protections for suspected terrorists, were introduced three years ago.
A company (170 troops) of Thai infantry crossed the Cambodian border near the Preah Vihear temple (which is right on the border). Thailand had seized the temple complex after World War II, when Cambodia was weak and disorganized. Back in 1962, an international court ruled that the temple belonged to Cambodia, but Thailand insisted some nearby land (4.6 square kilometers worth) was theirs. The temple was built by a Cambodian king. The dispute has simmered for decades, but earlier this year, Cambodia began pushing for more recognition that the temple was theirs. The Thais see this as a matter of national pride, and threatened Cambodia with military action. The 1200 year old temple is Hindu, dedicated to the god Shiva. Indians, and their Hindu religion, have long been present in Southeast Asia, and many Indian merchants and sailors married into the local culture (which is mostly Buddhist), but kept their Hindu religion alive. If it came to a war over the temple, Thailand would probably win. But international courts have consistently backed Cambodian claims.
Sounds a bit religious to me!
