What we won when all of our people united ... must not be lost in suspicion and distrust and selfishness and politics. ... Accordingly, I shall not seek, and I will not accept, the nomination of my party for another term as president.
When people have hope that their economic conditions can improve by simply working harder, they care less about politics and religion, they may not like many things in their society but they are unlikely to get angry to a point of violent uprising or dividing the country. When people feel stuck or when they are poor and do not have much to lose, they are more likely to rise against the people in power.
Without peaceful international relations, there could be no economic stability and prosperity. On the political front, world leaders and UN veto-holding members could reset their foreign policies and stop burdening their economies and their people with international conflicts. The UN international courts of justice could be responsible for resolving international conflicts. The implementation of this solution requires a strong global leadership vision and action. Unfortunately the US leadership is limited by many conflicting private interest groups and is buried in domestic politics, ideological conflicts, and security issues. It is also unlikely that the global powers will let go of their power voluntarily and the situation will not get better before it gets worse.
Yes, we have to divide up our time like that, between our politics and our equations. But to me our equations are far more important, for politics are only a matter of present concern. A mathematical equation stands forever.
