I have a question for those defending the US and Israel in the Iran war

Does this mean that from now on, China is also allowed to strike first and bomb elementary schools just like the US and Israel?
The biggest change since the Iran war is that China can now do whatever it wants without facing much resistance.
On what grounds, exactly, will China's tyranny be stopped?
Surely the US won't make the nonsensical argument that "it's okay for us to strike first, but not for you."
