Dark Forest analogy is totally misplaced. Dark Forest means that universe looks devoid of life but it's actually replete by it. The life is just careful to not reveal itself to strike first to kill and not be killed. IOW broadcasting information about Earth would be really stupid (too late, whoops!) But on Earth, US and China both know about each other, so there's no point in being "dark", they can both strike already.

I recommend Liu Cixin's trilogy Three Body Problem (third part being the Dark Forest). I listened to audiobooks.

> Of course, you may say, it’s just sci-fi. Yes, but "The Dark Forest" gives us an insight into something we think too little about: how Xi’s China thinks.

I hope the Chinese don't judge American attitudes to cooperation by Ender's Game...
