Yeah, I mean as far as we can see - which is a lot more than I thought with the last parade - China is ahead, though I am sure there were a couple of misdirects in there. Even just software / infotech wise, so far from what we could see, the Chinese have pulled ahead.
The only thing is that it is usually the guy that doesn't parade around for show, or has his dick out in public for all to see that you need to be wary of. The US has gathered a ton of data wrt drone warfare so far and I am sure they've been looking at that for quite some while.
I wouldn't be to eager to rule them out just quite yet, but at the same time the Superpower club needs more than one, the US needs an "adversary", not sure why, Americans be weird like that. But have you seen how they lost their minds once the Ruskies disappeared?
