Of course, although there have not been the global wars of last century, regional conflicts still arise, and the nuclear arms race continues. Easy access to images of atrocities carried out by individuals and regimes means we are no longer isolated, can no longer plead ignorance, and can feel like the world is a very unsafe place.
What to do when faced with such brutality? Leaders are damned when they do and damned if they don't act to stop slaughter.
Often, amid such stalemates and times of heightened unease, one organisation takes the flak: the United Nations. Most recently, failure to stem the violence in Syria has been laid at the UN's feet. Russia has been accused of (ab)using its Security Council permanent member veto powers to protect Bashar al-Assad's regime. In turn it accuses the US and its allies of abusing their power - acting without a UN mandate - in carrying out recent airstrikes.
It becomes easy, particularly when no simple solutions are available, to question whether the UN remains relevant.
Yet, as we once again come together to honour and remember the legions of soldiers - and civilians alike - who have died in conflict, it is vital also to remember and honour the organisation formed in 1945 after the devastation of another world war, whose raison d'etre is to maintain international peace and security.
Surely - and regardless of the failings - those ideals, and the organisation that best espouses them, remain worth fighting for.
