Having discussed the different types of states in Chapters 2 through 11, Machiavelli now turns to how to attack and defend them. Princes must lay good foundations, and those foundations include good laws and good armies. There cannot be good laws without good armies, and where there are good laws, there must be good arms, so Machiavelli declares he will only discuss arms, not laws.
Arms to defend the state are the prince's own, mercenaries, auxiliaries, or a mix of the three. Mercenaries and auxiliaries are dangerous and unreliable. If a mercenary is talented, he will always be trying to increase his power at the prince's expense. If he is incompetent, he will ruin the prince. Only princes and republics that can field their own armies can succeed, for mercenaries do nothing but lose. Those who are well armed can live free.
Machiavelli sites many examples of mercenaries who have turned on their employers. All this began when the Holy Roman Empire lost power in Italy and the popes gained power. Citizens took up arms against the nobles, and the popes encouraged them. Because neither the citizens nor the popes knew how to fight, they hired mercenaries. Soon mercenaries commanded every army in Italy. These mercenaries adopted strategies that kept them from hard work and danger, and this caused the ruin and humiliation of Italy.
This chapter and the two following concern arms and armies. It is tempting to interpret Machiavelli's quotable line that there cannot be good laws without good arms as just a variation on "might makes right," but this was probably not his intent. Because force is an inseparable part of the state, a well-governed state needs a good army. If the reader interprets "good laws" not in the strict legal sense, but as the conditions that make for orderly life in society, Machiavelli's observation loses some of its radical edge. Even in the modern world, the state that does not rely on police or military force to keep order and protect its citizens is rare indeed. Machiavelli further observes that where there are good arms there must be good laws, meaning that a ruler who is capable enough to raise and command a disciplined army must also be capable enough to keep his state well ordered.
Equally important is what Machiavelli chooses not to discuss. Just as in Chapter 1, where he declined to discuss republics, here he declines to discuss laws, confining himself to a prince's command of the military. However, the world he describes is clearly one of cutthroat competition and violence, in which only the well armed can live free. In such a world, the weak will quickly be exploited by the strong unless they can defend themselves.
"Good arms," in Machiavelli's view, can be only the state's own troops; that is, its own citizens, rather than outsiders. Keeping with his view that independence and self-sufficiency are the only security, Machiavelli asserts that dependence on foreign troops is the kiss of death to a prince's power. He had good reasons to think so, having observed the widespread use of foreign mercenaries in Italy and what he felt were its disastrous consequences. He blamed the mercenaries for lacking the spirit of soldiers who were defending their own lands and homes. In his opinion, the mercenaries were lazy, looking only for the easiest way to get their money, regardless of whether this benefited the state that employed them. They were also untrustworthy, because if they worked for a prince's money, they were probably just as willing to work for the prince's opponent.
Notice also Machiavelli's characteristic assessment of human selfishness: If you hire a talented mercenary who is successful, you will never be safe, because he will want to take over your position.
Mercenaries were common in the Renaissance. Ironically, the most famous were the Italian condottieri, sophisticated professional soldiers who spent their lives serving various employers. Criticism of them was commonplace and not necessarily always deserved, because many of them were highly successful and loyal to their employers' interests. Both foreign and Italian mercenaries participated in Italian warfare.
