The good intentions of the past

Sometimes we forget good things that have been done in the past. Take the link below for instance that I came across. It's all about the Kellogg-Briand Pact, which now forms a crucial cornerstone for international law. To sum it up the Pact, signed by scores of nations since it's first inception in the late 1920's, states that the use of war is, essentially, illegal. Of course this does not make defensive mitliaristic measures illegal, but invasions and other aggressive uses of military are thus classified. It would appear everyone had good intentions but we sure as hell haven't followed up with them. Here's the link to the full article on the pact.
