You are speaking of when Jesus was choosing the disciples who would follow him. One asked if he could bury his father first, and Jesus then replied, "follow me and let the dead bury the dead". Matther 8:22 He was referring to the spiritually dead burying the physical dead. There will always be war. One can only hope that we can somehow learn something from it...and while we are referring to scripture, the word also says that in the last days there will be wars and rumours of war. So it was, so it is, so it will be. Wars are orchestrated and we all know it. Order from Chaos.
