A low quality 9mm round can still kill you... And I don't think they're as "low quality" as you think. Japan wasn't anywhere after WWII, but now they are quite good at manufacturing quality products. China is capable of doing a lot of damage to the US, I'm sure about that. I just don't think they'll try. Even if they think they could win, it's just not worth it.Uncle_Sam said:China's economy is growing on the low quality things, China's weapons are produced in very low quality also. I wouldn't dare to get in Chinese produced plane.
My two cents
