I don't think one can reasonably compare modern democracies with universal suffrage, with the Roman Republic which had a much more limited voting population. Also the Roman Republic was, for much of its history, at war with his neighbors, so it had the civil structures and incentives (at all levels of the society) that went with near-constant war, so choosing to continue to go to war was an easy decision.
