can there be world civil war

The answer is yes, it seems. The terrorism that is talked about daily is a mixture of internal and external civil war. We have never really had a large worldwide civil war, but it looks like we are part way into one. Many of the terrorist groups have members from various religions, races, and backgrounds. There are many disaffected people these days that are looking for an avenue to vent their anger. I can't see that bombing is going to make much difference because these people own little property, and follow vaccuous causes.Even governments are at a loss at what to do to bring about order again. Perhaps a slowing down of world activity will do the trick, even a depression or restriction of money supply.
