Solution to war ?

Ii thought of a great idea to end wars.. its a bit simplistic but tell me what simplistic but tell me what you think We start the opposite of a terrorist group
A peace group.. It needs no coordination, no leader no meetings etc. All you have to do is sabotage all ammunition. Make every 10th bullet rocket weapon etc kill the person who shoots it
Then everyone would be afraid to use their weapons..It would sure put a dent in sensless mass killings although not in the short run Even in the most aggresive countries there would always be "peace warriors" who would infiltrate everything and work covertly because they wouldnt have a need to coordinate with anyone. just sabotage as much ammo as you can is the goal..
p.s. i am in now way suggesting anyone sabotage anything merely posing the question as a solution
