Nanaej, you have put it beautifully and poetically.
Sometimes war in other countries far away does affect us. Many,many Islamic terrorists have been trained in Afghanistan. The man behind the group who attacked the gas plant in Algeria and killed, among others, British citizens, received his initial training in Afghanistan. So have a number of our home grown terrorists.
'How horrible, fantastic, incredible it is, that we should be digging trenches and trying on gas-masks here, because of a quarrel in a faraway country between people of whom we know nothing..' Neville Chamberlain's words in 1938, but because we did not oppose the Nazis then they felt they could with impunity take over Europe and we would do nothing.
What people forget is that when deciding whether to opt for war or peace, the peaceful choice kills people as well. When I was opposed to the war in Iraq I knew that by my opposition I was condemning to death people in Iraq whose lives may have been saved by the war.
