The primary virtue of the young man is Courage. It is beautiful to see the portrait of the courageous young man, and as long as history records (and it is suspected much much longer), the primary avenue with which to demonstrate courage has been in going to war. Memorial Day is best liked as a tribute to the virtue of courage as exemplified by young men going to war...and as a tribute to those who have lost their lives in demonstrating said virtue. I honor these young men, and particularly their courage, but also their ability to work together to solve hard problems against determined opposition.
On the other hand, waging wars of aggression upon other countries is not among my list of proper functions of government. The last war that we collectively engaged in defensively was (arguably) Japan in the pacific in the 1940s. Before that, 1812 was the last defensive war for the Union*. While the men demonstrate courage, I cannot say that our political leaders are lily-white, pure, or otherwise even good. And the wars, skirmishes, and police actions we collectively engage in are quite far from obviously in the best interests of the people of this country.
I therefore respect mightily the courage of the young men, and now women serving in the military. And I regret mightily their decision to harness their courage to the evil aims of the government. But this is Memorial Day, and the order of the day is the remembering of the dead men who demonstrated courage, and died for their demonstration. And there is good reason to remember their sacrifice. In memoriam.
