If I recall well the argument, the whole point about war is that it serves as a counterbalance against the problems that perpetual growth brings. It is never truth that the war is economically productive. But the destruction of capital that comes as a side effect of war keeps inflation on check (monetary inflation defined as money growing faster than the tangible economic output; not price inflation, which is one result of the former). Besides that, while it might be a net negative economic event, War puts lots of public money in some chosen private pockets. So there are always people lobbying to get into conflict in a perfectly rational way.
