[R. vs B.] Nuclear warfare - ProjectQ

R. Blue and N. Red have been rivals since they were born. What started with stealing eachother pencils at school ended in a nuclear warfare. With the help of J.K. R. Blue started the development of massive destruction weapons to get rid of N. Red for once and for all. N. Red didnt agree to this and hired Italian, as everyone calls him. Italian stole some of the weapons from R. Blue and sold them to N. Red, also he used the weapons to create improved versions to break the limits of J.K.'s weapons. Now those two use all the armys and weapons against eachother as mutch as they can. The question is, with this powerfull weapons, how can it still be both of the company's excist?
