To be fair, in the modern international climate, we've seen that wars between developed countries have dropped off drastically because of the development of nuclear weapons and the creation of MAD. There are few truly formidable defensive structures from the past 100 years - the circumvented Maginot Line and the overrun encampments on the beaches of Normandy come to mind. The point being that it doesn't seem unreasonable to expect that a legion of military minds trained in deterrence as the primary response to threats from rational entities would think first to build the capability to retaliate and second the capability to defend. I'm not really sure how far the comparison between physical military threat and cyber threat really carries, though.
