Has there been any war worth commemorating ?...to answer that we should look to reasons if any the war broke out , and what the outcome meant for the victor. WW1 was a pure folly destined to happen if you study the way the great nations postured and allianced in the lead up to 1914. As such I tend to agree we should somberly remember the millions of innocents whose lives were casually thrown away by the idiots leading us.
WW2 is completely different . That was fought for freedom of the world from dictatorial/ imperialist oppression.More people died, but there are firm grounds to argue it was for the betterment of mankind.Ironically we tripped into this war through our alliance with Poland, but its hard to argue Hitler would not have consumed us had we tried to stay out of it , as so many countries found to their cost.
