Random Thoughts...on Nuclear Warfare!

According to my brother's magazine, Popular Science, the British Ministry of Magic Defense has invented a shield for their tanks that explodes any shells that come up against it...so what does this mean practically? People will stop sending bullets in war (aka conventional warfare) and will have to move on to non-conventional methods that can't be protected against...like nuclear, etc. Doesn't that make you feel all warm and fuzzy inside? :)
