There is certainly some disparity between fighting for a great cause and fighting a useless war.
I suppose that it is all in perspective, because to one man a war is a worthy cause for liberation while to another it is an oppressive power grab.
We must each make our own decisions, because it truly seems that war is inevitable (whether physical war or the daily mental battles we face).
I agree diplomacy and compromise is ideal, but most importantly we must all understand our values thoroughly and only fight when we truly believe in the cause.
Great read from your 14 year old self! Thanks,
