The only thing that will stop Iran from getting a nuclear weapon is the destruction of Fardow.

The only thing that can destroy Fardow is the GBU-57

The only country that has a GBU-57 is the US

The only thing that can deliver a GBU-57 is the B2 and B-21

The only country that has a B-2 or B-21 is the US

Donald Trump said Iran is never allowed to have a nuclear weapon

Yes we are 100% going to attack Iran/Fardow and nothing can ever change that unless Iran surrenders (they wont).
