Terry Duncan wrote:The moral judgement on war pretty much started with WWI, though it is still the winners who were innocent and the losers always guilty, today nations don't even bother with declarations of war in order to be able to maintain the notion they are peaceable and only resort to use of violence against 'rogue states' or similar. Germany opted for war, she lost, therefore the decision was a poor one.
Not sure I agree with that. The moral judgement on war goes back much further: St Augustine coined the phrase the just war. Thomas Aquinas set out criteria that still have relevance. Proper authority - for a good and just purpose and with the aim of restoring peace. These criteria framed public christian responses and international opinion.
The French revolutionaries were in the wrong to depose their king. The European monarchies had a just cause to fight the revolutionaries. Napoleon was morally in the wrong to invade Russia. German stares were fighting a just cause to eject Napoleon from Germany. Not saying that I agree with the logic, but it was influential and framed thought before and during WW1.
For what its worth the Germans had as much of a cause for supporting Austria-Hungary's War on Terror in 1914 as Britain did supporting American intervention in Afghanistan, and much less for the intervention in Iraq in 2003. But justice is a compromise between morality and expediency.
