The US and Iran have been at war for 12 days, and the PLA has at least confirmed these four things:

1. The Americans still do not have highly effective countermeasures against drones;
2. The Americans still cannot efficiently intercept hypersonic weapons;
3. If the conflict drags on a little longer, the whole world won't be able to take it;
4. No matter how well the fighting goes, the Americans always have a way to bring themselves down.
