I try to stay out of such debates in attempting to say who has what when it comes to things classified. We really have no way of knowing. I believe we are barely on top, but the Chinese have the labor, patience, and political focus to pretty much do as they please now. I wouldn't be surprised at all if they top us in nearly all technology by 2020. We have too many people with that lazy mentality here, and too many politicians buying votes with our tax dollars.
Again, think "
