What is the most dominant and effective fighting style in the world?

You and all the answers overlooked Krav Maga.. let me tell you why.. Although i concede that a fighter makes the art, the one true form in my opinion of COMPLETE dominance is the israeli Krav Maga.. it is being utilized by many other countries in their defense programs including our own special ops. It not only incorporates stand up and grappling, but weapons as wekk, and the sole purpose of it is to incapacitate or kill an opponent as quickly as possible. I believe it is the most feared martial art and that is why our government and others train our elite commandos and spies in it.
