This reminds me back in the elementary school days where few new kids were trying to challenge the “king" of the playground. There was a lot of unease and there might even be few bloody noises. At the end of the year, guess what, we all graduated to middle school. When we think back the good old days today, everyone just can’t stop laugh about the silly stuff we use to do to each other.
It takes the US 250 years and China more than 70 years after WWII to reach where we all standing right now. Despite the few differences here and there, the overall relation between the US and China is overall peaceful and in harmony.
If all we focus on are the negativities, after a while all we see would be the negative image of the other side.
There is so much we can achieve through cooperation, and we should never forgot about that. On daily basis, the amount of cooperation between the US and China far outstrips the little difference many people keep focus on.
