I think he has a verry good point there. Imho many people, unlike their parents/ gradparents, have forgotten how brutal and unraveling war is and how much suffering it brings upon others which lose dear family members and/or their health.

This might be largely due to mass media showing only piles of rubble and not the human misery underneath and infront of it because it’s deemed ,to upsetting" for the broad public. But that misery is on of the core points why we once intended to end all wars. There are exceptions of course (like some well made documentaries) but one has to actually search for them and expose oneself willingly… when in reality the matter should concern each and every one of us.
