I believe in the pre-World War I Republican policies that led to a highly developed industrial economy with few commitments to international security. We are at risk from China because we outsourced our industrial capacity to China. The U.S. used its industrial capacity to build the largest air force and navy in the world overnight when it entered World War II. Today, China is the country that has that capacity.

Ok. So if we really did care about building that industrial capacity, then why are we randomly and capriciously taxing the resources needed to build that capacity? Including the critical resources that we don't have in America? Why are we making it so hard for domestic production companies to make short, medium, and long term plans by repeatedly changing our trade policies on whims?

The globalized supply chains needed to get the natural resources alone should be enough to answer your question about why we should care about America's global relationships.
