The corollary to my point is that it does no good for the Cannanites to abandon their expansionist ideology unless they can ensure that the Israelites, Philistines, Egyptians, Assyrians, and everyone else also commits to peace as well. In the absence of a general forswearing of expansionist ideologies, one faction committing to abandoning expansionism is unilateral disarmament.
We actually have an example of this: Japan. From 1633 to 1639 the Tokugawa Shogunate imposed a set of policies that banned expansionism, foreign trade, and expelled representatives from European countries. In the process, Japan gave its up its firearms and reverted to the sword. Because Japan was an island nation, without any major known natural resources, far from the then-existing trade routes, they were able to get away with this policy for quite a long time. But quite a long time isn’t forever, and in 1854, the outside world came knocking.
Japan switched hard from isolationism to expansionism almost immediately after the Meiji restoration. This started with the first Sino-Japanese war, in 1894, during which Japan invaded and annexed Korea. This continued with the Russo-Japanese War of 1905, where the Japanese defeated the Russians and took control of Port Arthur and the Sakhalin Islands. This continued with the Japanese invasion of Manchuria in 1931, which eventually bled into World War 2 after the Japanese preemptively attacked the US in order to enable their expansion into Southeast Asia.
During this time, the Japanese self-consciously adopted the ideological, governance and military structures of expansionist European nations in order to avoid being left behind and dominated. That’s why the Japanese parliament is called the Diet, a German word. The Japanese Navy was explicitly modeled after the British Navy.
It was only after the Japanese were thoroughly defeated by the United States and Soviet Union that they transitioned to their current model of focusing on commercial success over military expansion. They were able to do that because, in the wake of World War 2, they were given explicit security guarantees by one of the two major global hegemons at the time.
