Often a war is cloaked in patriotic terms as defending the country against foreign enemies, but the war is often not fought on the land of foreign enemy or even the land of the country claiming defense. The war is fought on lands either loosely allied with one side or the other or even on lands that would rather be neutral.
Those who are opposed to these wars are often called unpatriotic, but they may really be the patriotic ones who see the folly in expending lives and treasure. These "unpatriotic" may be executed or imprisoned in some countries or may be sidelined or ostracized in more "gentle" countries.
Some wars are instigated for conquest and masked as being for the greater glory of the nation. Anatole France, commenting about past French wars in "L'Île des Pingouins" could just as well have been predicting Adolph Hitler. A visitor stood in front of a statue of Trinco. Trinco has conquered and lost half the known world in thirty years of war. The guide finishes a description of Trinco's victories and defeats with, "Mais il nous a donné la gloire." The visitor responded "Il vous l'a fair payer cher!" And the guide responds "La gloire ne se paye jamais trop cher."
"But he gave us glory."Some wars are fought for a "national interest" but cloaked as a defense of freedom. The national interest could be protecting shipping, access to resources, or some other interest for which the greatest beneficiaries are nowhere near the front lines. Ironically, to protect freedom the freedom to protest the war is the first freedom to go.
"He made you pay dearly."
"One never pays too dearly for glory."
The true test of the value a nation places on its heroes is how the veterans of war are treated when they return. Is the country willing to raise sufficient funds to fully treat all physical and psychological injuries? Think of Ira Hayes, fêted as a hero until he lost his usefulness as a war bond promoter. Think of the dismal state that Walter Reed Hospital was in a few years ago. Think of all the homeless vets who just can't make it on their own. Until a government fully addresses these issues, many of its heroes are victims of the folly of war.
