I never thought it was a good idea to go to China and teach them how to make things using modern manufacturing techniques.
Nixon went to China as a symptom of weakness, not of a manifestation of strength. He was hoping to use his Chinese diplomatic success to bolster his administration, which was under attack from leftists. It cost us industry, after industry as greedy globalists sought the low cost providers.
If anyone thinks the Chicoms will ever allow modern assembly machinery that was installed in factories over there be disassembled and shipped to the US, they had better think again.
