have saved him; and conquering, as it is impossible that he should not do with your assistance, he remains at your discretion. And here it is to be noted that a prince ought to take care never to make an alliance with one more powerful than himself for the purposes of attacking others, unless necessity compels him, as is said above; because if he conquers you are at his discretion, and princes ought to avoid as much as possible being at the discretion of any one. The Venetians joined with France against the Duke of Milan, and this alliance, which caused their ruin, could have been avoided. But when it cannot be avoided, as happened to the Florentines when the Pope and Spain sent armies to attack Lombardy, then in such a case, for the above reasons, the prince ought to favour one of the parties.
Never let any Government imagine that it can choose perfectly safe courses; rather let it expect to have to take very doubtful ones, because it is found in ordinary affairs that one never seeks to avoid one trouble without running into another; but prudence consists in knowing how to distinguish the character of troubles, and for choice to take the lesser evil.
