Nobody serious disputes that Iran was enriching uranium, and to levels far more than needed for nuclear reactors, and to close to the level needed for nuclear weapons.
That enriched uranium exists. "Iran wasn't building a nuclear weapon" doesn't change that.
This discourse on military action seems to be incredibly misinformed. I think some people only know how to think of any military action in terms of "is this like Vietnam, or is this like Iraq?"
Or Afganistan.
War is murder.
This is the #1 indication of just how primitive our violent ape species still is...
