This attitude leads to generals sabotaging the Christmas Truce and way more deaths than necessary. Very very few wars are against invaders who want to kill everybody.
I cannot put into words how revolting this idea of yours is, and it's exactly people like you that need to be silenced in times of war for any chance of durable peace.
War is always and everywhere a result of insufficient deterrence - the enemy will only be dissuaded if they are guaranteed a response that far outweighs any potential wins.
World War 1 killed a lot more than 1% of the involved population.
Honestly, just giving up and "losing" WW1 would have been way less bad for the commoners than actually fighting was.
The problem with wanting to fight wars is that deterrence doesn't work (e.g. see the past 10 wars). The incentives leaders are subject to often makes starting a war the best option for them personally, even if its bad for the population.
Btw: its exactly warmongers like you who need to be silenced to have any chance of a durable peace that doesn't kill a million Iraqis ;)
I know you are well intentioned and believe in the things you say, but you should probably think this stance more thoroughly.
