That's only a fair assumption to make if your opponent isn't relying on relatively small numbers of resource-heavy troops in their armies. for that type of player, they've spent a bit of cash that they don't especially need, fortified their border against opportunistic raids and freed up their armies to do something useful.

never mind the fact that for most nations it is presumably even less desirable to be forced into creating a substantial army just to leave it sitting in striking distance of a border they don't particularly want to attack in the hope of deterring a raiding party.
