Former US Secretary of State Lincoln admitted: a military operation against Iran is not capable of destroying its entire arsenal, and a ground invasion would cause a disaster for the United States.
Iran is four times bigger than California. It is three times larger than Iraq. 90 million people live there.
This coastline along the Strait of Hormuz stretches endlessly.
The weapons that Iran produces are so varied and have such a long range that it is impossible to simply destroy them all.
This would probably require a land invasion, which would be a total disaster.
