The correct answer to this open question is the following.
Indeed, there is no question here, It is an affirmation.
Doing some research we find that the question that is missing is:<em> "Do you agree with him?"</em>
If that is the case, we can answer the following.
First, let's have in mind what John Locke wrote about the war in his treatise "Second Treatise of Government." He said that he supported the war but in equal or similar conditions between rivals. He appealed to the Ethics of war saying that waging war with a weaker rival was not just or moral.
With that in mind, I can say that in whatever form, war has never been the solution for conflicts. On the contrary, it only creates pain, deaths, damage, and so much destruction. That has been the history of humankind. Most of the time, nations wage war to exert power and control over other territories or exploit their raw materials.
