to make sure it doesn't happen again and the best way to do that is to keep reminding ourselves of what happened and why

It will happen again, Jim - again, and again, and again - and for the very best & worst of reasons as we struggle towards some ultimate enlightenment where we might, at last, live in peace. Until such a time (someway off yet I fear!) be respectful of the sacrifice of those to whom we owe our present freedoms, however so imperfect they may be.

Far lass comfortable than paying lip-service with a poppy, minnd you

The ultimate comfort is the mawkish sentiment of the anti-war songs under discussion here; it's a sucky-blanket dream that belittles the horror of war by denying its terrible reality. It will not be washed away by the crocodile tears of a dozen or so peacenik folkies in their self-appointed moral superiority, for its measure is the millennia of aching sorrow that such sacrifice was not only necessary but risen to. That's why I wear a poppy. A simple gesture to a reality I cannot begin to comprehend.
