There are times, I believe, when a nation must take to arms for absolutely legitimate reasons. Invasion is certainly one of those reasons. Ego gratification is not.
What we now call World War One, what was once called The Great War, started because of happenstance and lunacy. It became the most horrific spectacle of the 20th century because a very few number of leaders (none democratically elected) thought virtually nothing of the lives of their subjects, and cared very much about their own personal standing in the world.
Unprepared for the demands of modern warfare, military commanders blithely sent wave after wave of young men against poison gas, artillery and machine guns, then the newest weapons of mass destruction, into the certain death of direct assaults against fortified positions. Before the carnage was over, there were 35 million casualties, of whom 7 million were civilians. Cities fell to constant bombardment. Death and destruction on an unimaginable scale.
The nations of Europe lost an entire generation of young men. Empires, that had sought to improve their standing in the world, collapsed. Maps were redrawn. That continent changed, more or less, permanently.
And there were the waves of war-scarred veterans returning home, changed, more or less, permanently as well. Sullen. Withdrawn. Drug-dependent. No longer able to fit within the societies they’d left.
As we Americans consider our next use of our armed forces, we would do well to ponder Europe’s ugly history of military adventure directed toward achieving uncertain aims. For unleashing weapons with illegitimate reasons, there is hell to pay.
