What steps did world powers take after ww1 to avoid future wars? Why?

In the Treaty of Versailles, many European powers concluded the war was due to German aggression and established the League of Nations.

Explanation:

What they did plan for a heavily weakened Germany as both the Austrian-Hungarian Empire and Ottoman Empire collapsed. Germany's Army was downsized to only serve as a defense force and its navy and airforce were abolished. They thought if they could weaken Germany with all of these punishments it could never rise to power like it once did pre-ww1. Not only did the restrictions on the German Army took a toll but the heavy war reparations that the German Weimar Government could never repay. When the League of Nations was established, they had been a counsel of country representatives and diplomats to resolve foreign problems without the means of war. The League of Nations had no army force itself and could not enforce sanctions either like today's UN making it virtually useless. Even the creator President Woodrow Wilson did not bring the US into the League of Nations.

Key Points:

-Weaken Germany's Army & Economy

-League of Nations to ressovle foreign problems

relations between the soviet union and the united states were driven by a complex interplay of ideological, political, and economic factors, which led to shifts between cautious cooperation and often bitter superpower rivalry over the years. the distinct differences in the political systems of the two countries often prevented them from reaching a mutual understanding on key policy issues and even, as in the case of the cuban missile crisis, brought them to the brink of war.

the united states government was initially hostile to the soviet leaders for taking russia out of world war i and was opposed to a state ideologically based on communism. although the united states embarked on a famine relief program in the soviet union in the early 1920s and american businessmen established commercial ties there during the period of the new economic policy (1921–29), the two countries did not establish diplomatic relations until 1933. by that time, the totalitarian nature of joseph stalin's regime presented an insurmountable obstacle to friendly relations with the west. although world war ii brought the two countries into alliance, based on the common aim of defeating nazi germany, the soviet union's aggressive, antidemocratic policy toward eastern europe had created tensions even before the war ended.
