"If the US military/domestic situation does not allow the secondary objective to be pursued, then we may pursue the course you propose. But it will only delay the accomplishment of the secondary objective, which must still be accomplished"
I have to agree with you. I was assuming the primary objective is so critical, we would jettison the secondary one to achieve it--without impacting our mission in Iraq.
I would love to see Iran return to a modern, pro-western state, only this time, a republic.
So would a great number of its citizens and expats.
