Good idea Vino, I'll just pop in my Tardis & go back to the 30's to the early design stage of the magnetic exploder and convince them the user should be able to select between magnetic & contact detonation! I wouldn't at ALL be motivated to correct the problem entirely, after all SHIV is the important thing!
Actually, if I were feeling whimsical and could manipulate time & space, after a lifetime of preventing horrendous evils I'd just want to make a universe where Cindy Crawford, Rita Hayworth & Liv Tyler knew my name. I'd call that a good day's work.
