I think the interesting part is just how deeply embedded China is in the supply chains for everything nowadays. Figuring out what parts are ultimately sourced from China is actually pretty difficult, and since US lacks domestic manufacturing capacity to have fully controlled domestic supply chains, it's in a vulnerable position vis-a-vis China. If US continues to escalate the trade war then China's response can be catastrophic for US economy, and if US is insane enough to actually goad China into a war then much of its military equipment may be vulnerable.
