You’d need to define what you mean by Machiavellian tactics. Machiavelli was the first political scientist after Aristotle, and arguably the father of politics as a scientific endeavor. He entreated rulers to move away from ancient traditions, religious or abstract moral principles, to material, logical, evidence based, principles necessary for the state to persist in the interests of its citizens. At the time of his writing, trade was moving north, and the principalities were being both threatened externally and undermined from within. In this sense, almost all political action in the contemporary world is Machiavellian.
So if you mean some other sense, then state it, and I’ll try to answer.
