One possible point to consider is in America pulling back all the US corporations that have skipped town and went to China. That would be very painful for Walmart and co. but Cold war relations with China would make it necessary nonetheless. Also, China has the power and the clout to go tit for tat.The wars have forced the US to enhance technology and we did. However what you say is only part of the picture.
Corporations, the government, and the citizens favor short term gains over long term prosperity.
