Which is true about the kellogg briand pact of 1928

Here are two truths about the Kellogg-Briand Pact.
1.  It wanted to outlaw war, so that nothing like The Great War would ever happen again.
2.  It failed to have any real impact in keeping nations from pursuing war, and we now call "The Great War" World War I, because it was followed by World War II.

French Minister of Foreign Affairs Aristide Briand and US Secretary of State Frank B. Kellogg were key proponents of the plan, which was signed by various dignitaries at the White House in 1928.  The pact stated that the signing nations were "persuaded that the time has come when a frank renunciation of war as an instrument of national policy should be made," and so the signers of the treaty declared their opposition to war.  By their example they hoped to encourage other nations of the world to join them in the same commitment.   

The pact had little effect.

The answer is installation.
