I'd like to suggest a pause to consider...
Perhaps dividing the world into good people and bad people, then justifying killing the bad people...
...is not part of the solution..
...and even as I write this, I must admit that one thing we perhaps all have in common, whatever position we take, is that each of us believes we're 'on the side of the angels'.
Perhaps we might put ourselves in the shoes of those we disagree with here on this thread, and admit, even if only to ourselves, that there may be some way in which they may have a point.
Whether we're Arabic or Jewish, Israeli, Palestinian, Lebanese, British or whatever - we all hurt when we're attacked, and are all furious when those we're allied with (in whatever sense) are torn apart.
Perhaps stretching a little grown up compassion for the other may be helpful...
