Yesterday's debate, and the debate generally over the past week, has been about the morality of war and the morality of countries like Ireland getting involved in war. I wish it were otherwise, but morality has never been high on the agenda where international diplomacy is involved. The last century has seen wars started and countries squashed and run out of existence because of big power claims. It is astonishing to think that, at the start of the Second World War when Nazi foreign policy was to wipe out bolshevism or communism, they signed the infamous Ribbentrop Pact with the Soviet Union when both countries were eyeing up for war. There was no morality in that – it was all about grabbing land and territory, taking Poland out of the equation. It was about Soviet hegemony and Nazi Lebensraum development to the east.
