What urgency? Why would Iran launch a missile at Europe? There is Zero chance for that. Zero. The Europeans have been their best customers. The Russians are their major business partner and an attack on Europe spreads poision over Russia.
Trying to draw the Europeans into this is ludicrous.
Where's the launch pad? The silo? This looks like if anything an assembly facility.
But we know Iran has medium range missiles already and that they will continue to improve them.
If they develop ICBMs the upshot is that they have a deterrent. We can no longer threaten them. They can play the crazy angle and adopt the MAD posture that we had during the Cold War.
If you want Iran to relinquish its nuclear program then it has to be a regional effort and include bringing Israel's nukes under international monitoring as well.
No self-respecting country is going to sit still while enemies point nukes at its capital and park aircraft carriers off its coast.
You want progress? Start dealing with them like adults and recognize and incorporate into the equation their own legitimate security concerns.
You want the status quo, you want the Iranians to do whatever they need to do counter US and Israeli threats, then maintain the status quo.
