One of the most important components of world justice and peace is to have elections monitored and certified by an international organization in every country.
A big step in the right direction, and a relatively easy step, would be for the United States to set an example by inviting monitoring of our elections.
I do not say this because of the serious questions surrounding the last two presidential elections in America. The United States can take the approach that we know our elections are sufficiently fair, but that we want all countries to be monitored and certified, so we will have ours monitored as well.
Hopefully other countries would follow, first strong democracies that have little to fear from monitoring, and after we reach a critical mass, other countries who would feel ashamed to be out of the system. Eventually there could be some international repercussions for countries that did not accept monitoring and certification.
