What were 2 measures taken to ensure lasting peace throughout europe following ww1?

A meeting at Paris was held and a treaty was signed..

And the blame was left on Germany aggressiveness..

Explanation:

The main terms of the Versailles Treaty were:

(1) the surrender of all German colonies as League of Nations mandates;

(2) the return of Alsace-Lorraine to France;

(3) cession of Eupen-Malmedy to Belgium, Memel to Lithuania,

The required treaty for the army and standards to the treaty to take place in which Congress did not allow certain actions to occur while other countries did not agree to such

Germany opposed the treaty because it blamed the war on them. Colonies in Asia and Africa opposed the treaty because after helping fight the war, they were not granted what they traded for when fighting for the war.

might be agreeing to participate ethically with other european nations in the slave trade

or notifying other european nations when taking possession   of african territories

honestly you should get that checked out because it really isn't normal
