> We stopped letting them manufacture anything of strategic military or government significance. We are mostly dependent on them for basic household goods and consumer electronics. Those things could be cut back significantly without destroying our own economy.
That dependence still creates a significant political risk, which the West is in a poorer position to manage.
> Keep in mind that China can't feed itself without the world. That is a much more dangerous dependence.
That would be a serious vulnerability, except the world probably isn't united enough for it to matter. For instance, my understanding is Russia is a major food exporter. Add in a conquered Ukraine and maybe a couple other countries and you might fill that gap.
