Literally just TWO days ago China was publicly flexing their ISR capability. On the 26th they published maps and photos of where the US's most valuable fighter just were stationed.
The US flew hundreds of flights over the last week to move these fighter jets and their support crews into theater.
It's clear China has the ability to track US assets in near realtime and likely published these maps as a deterrent.
So I've been digging through the OSINT on the brewing US conflict on Iran for basically the last month and another aspect I've been keenly watching is the sale of Chinese made anti-ship missiles to Iran.
Having high quality missiles used to be unique to the US, but now EVERYONE has missiles.
And the problem is that missiles are a massive existential threat to US carrier groups.
