Nobody knows what's going to happen. A conventional war is just too costly for both sides. Yes, china does own US treasuries what is money but only a form of mutual agreement between parties? You can't just dump those treasuries and close off the US market to the rest of the world. Who is going to pick up the slack in demand in case that happens? Europe can't, Russia can't, the middle east can't... maybe Africa can? But it is still too premature to even think about it.

No one consumes goods more than the Americans.

But if you think about it, this arms race with matching technological innovations will provide a niche which is slowly becoming mainstream. The more conflict arises the more innovations and fierce competition.

Just don't be left out.
