A Noose Made of Filament

The growing list of sanctions against Russia, because of Russian efforts to annex parts of neighbor Ukraine, have hit the Russian arms industry particularly hard because new Russian weapons depend on Western suppliers for some of the high tech components needed. China is taking advantage of this by pointing out that China has become a major producer of high end electronic and mechanical components and can probably replace Western suppliers now unavailable because of the sanctions.

China gets richer, Russia gets weapons, we lose business, and Ukraine remains screwed.

Sanctions are a deeply unserious way to prevent or stop a war.
