No matter how the war in Ukraine goes, China's advances are inexorable and our loss of assets, financial, allies and military, leave us more and more naked. China has become the "arsenal of Communism".
AND they own many of our politicians.
AND they don't have a problem with massive immigration by Third-World morons.
AND they have three times our population.
AND they have infiltrated our Universities and corporations.
AND they (with India) produce most of our antibiotics; and they produce many items vital to our infrastructure for which we have NO replacements (electrical transformers).
To your point, I can think of no major, critical or essential American institution, whether public or private, that has not been infiltrated by the Chinese. The question becomes can we identify those institutions that stand between us and a modern yellow peril that have not been suborned and rendered worse than faithless?
