Look, SFB, so what you are proposing is that you wait until they DO, then have a real chance at holding Europe, Asia and America hostage? By a country who has vowed our destruction as their primary aim for half a century?
The already had over 900 pounds of 60% enriched U235 which is weapons grade and rather easily spun up to 85% or higher in a short time, enough for 10-12 atom bombs the size of Hiroshima, and now they reveal intermediate range missiles easily capable of hitting Paris after telling us they didn't have half of that range capability.
They lied once, who is to say they don't have missiles with even greater range they have not yet revealed?
We stood on the precipice of a mortal enemy having nuclear strike capability against the West, an established habit and intention to use its military power to bully others and hold oil hostage, no regard for even its own neighbors or people, and the cornhole is trying to us now that we were premature in going into Iran in an unjustified military action and should have just left them be, waited a few more years and hoped for the best?
