... If instead of colonies you send troops, the cost is vastly greater, and the whole revenues of the country are spent in guarding it so that the gain becomes a loss, and much deeper offense is given since in shifting the quarters of your soldiers from place to place the whole country suffers hardship, which as all feel, all are made enemies and enemies who remaining, although vanquished, in their own homes, have power to hurt. In every way, therefore, this mode of defense is as disadvantageous as that by colonizing is useful.
— Niccolò Machiavelli
