To respond to these thoughtful remarks, and even the unthoughtful ones, let me make a few quick points: --A blockade of Chinese ports would be an act of war. What insanity to even think about that. Whoever is promoting that idea is nutso. --For a while, it looked like American companies could make money in China and that doing so was compatible with broader American goals of greater pluralism in China and of creating a global partnership built around the world order we had established after WWII. Those goals have now been destroyed, so when American companies sell equipment and services that help Xi Jinping maintain his digital dictatorship, it's a new world. I think American tech companies are going to come under big pressure. --We don't have the leverage to use South African apartheid type pressures on China. They are the second largest economy in the world. They're sitting on roughly $3 trillion in foreign exchange reserves. --I take the point that Wall Street isn't a monolith. But our financial players have been lured into investing billions of dollars in China. The Chinese see them as a useful tool for policy leverage. If JP Morgan Chase comes to Biden and says they are at risk of losing $5 billion in China and that might affect U.S. financial stability, what will happen then? Who will drive policy? --Lastly, since we lack any real influence, the best thing we can do is to get our own house in order to compete. This was the "competitiveness" argument during the Great Japan Debate of the late 1980s. We have to become more coherent, focused on the long-term and actually cooperate with each other to create stronger technologies that comply with our social and political goals; to harden our IT systems which the Chinese have deeply penetrated; and create a sense of unity and urgency among the American people. There is a lot that can be done. And must be don.
