China, Iran and Russia can vastly out produce missle interceptors. Drones, hypersonics, etc.

They can also manufacture launchers faster and cheaper than they can be countered. $30k drone vs interceptor at millions.

The U.S. and Israel will not accept the current regime staying in power.

Neither side wants to stop the war. Israel, Europe, the U.S., gulf states and others in missile range of Iran will not want the current regime to remain in power.

What happens next? Full invasion? Regime change Iraq style??

Here is a highly probable outcome before next year. Iran continues breaking the Iron Dome and firing on "allied" targets and infrastructure. The U.S.refuses or cant sustain a full invasion (because it is a death trap).

What happens next? It is obvious Israel will use tactical nukes on Tehran and other targets in Iran. It is going to be their only option.
