What we also need to remember, now more than ever, of why war is a Very Bad Idea. And how one should never engage in it without consideration, and how it should be a last resort. Some actions are such that the only possible response is war. But others...options need to be explored thoroughly. It is a solution of death and maiming, on both sides. A solution of destruction and attrition. That seems to get lost in ideology and jingoism, sometimes.
And so we should remember, remember it all.
