I hope every single Western Military planner think like that so US ally armies probably get decimated in a future war. China has been selling military hardware since the 60s, from combat jets to Cruise Missiles to drones to AKs. From Guerrilla Warfare to Big shooting wars like Iran-Iraq. They evaluate directly and indirectly the performance and the use of each weapon and incorporate that in their training doctrine. The Pakistani air victory against India was due Chinese and Pakistani air force training together incorporating the lesson of past air battles between India and Pakistan. The French didn't that with the Indian. China is clearly evaluating the success of Iranian missiles in Israel, who defeated the most advance air defense system, ever, China has the largest most comprehensive missile arsenal ever. The Russia-Ukraine-Mossad drones are made with Chinese components, imagine how much advance Chinese FPV drones are going to be. Chinese are not only going to be more unjammable but also incorporate automated targeting features and swarm intelligence.
And the Chinese are also are going to evaluate, if the Iran-Israel war extend, the use of Iran Noor anti-ship cruise missiles. A version of China 802 anti-ship cruise missile. As a "PLA watcher" you should pay a little more attention.
Exactly, US B-2 and F-35 have never been tested against real air defenses
