You can beg to differ, nothing wrong with that, but there is a thing called "blow back", so as far as some claims, as they can get a bit crazy, there are added chemicals in mix to accomplish the most harms, it's just not comprehensible to the overall threat it would also pose to the one's masterminding it, their family and loved ones. Just wouldn't add up wanting to harm your own family. Also, you should look up how many rockets go off globally each year, it's an astonishingly impressive number that unless one looks, can't comprehend.
