One hundred years ago the War to End All Wars--or as we know it in retrospect, World War One--ended as the armistice to stop the European bloodletting began.
It was our first direct intervention to prevent a hostile power from controlling Europe's large reserve of military, economic, and scientific power.
World War II and the Cold War were subsequent efforts to keep Europe from being controlled by a hostile power.
And while Europe is declining as a military and economic power, it is still necessary to keep the continent west of Russia on friendly--or at least non-hostile--terms. Which is why I strenuously oppose the European Union political project that would turn the trade bloc into a multi-ethnic empire that tramples on democracy to keep member states from exercising authority.
Let's not waste the financial effort and sacrifices in lives we've made for a century now.
And may we never have a World War Three, of course.
