Did Rousseau think only president should declare war?

Jean-Jacques Rousseau did not specifically argue that only a president should declare war, as his political philosophy focused more on the concept of the general will and the social contract. He believed that the power to declare war should ideally reflect the collective will of the people rather than being concentrated in the hands of a single leader. Rousseau emphasized the importance of civic participation and collective decision-making in matters of significant state action, including war. Thus, he would likely advocate for a more democratic process rather than exclusively presidential authority.
