This is a reasonable possibility—given the political environment of the times.
The only question I would have about it would be why would the Iranians not brag about their success—they loved issuing press releases attacking the “Great Satan”.
If Clinton and the Europeans wanted to cover it up that would be even a better reason for bragging about it.
I am told that the Iranian government had no role in it, and they were scared sh*tless that they would have been thought to have been involved in it.
They talk loud in public, but the idea that the US would be coming after them for blood is something they very much don't want to see. The 1991 gulf war showed them how fast we could wipe out another country's army. They fought Iraq for years and only achieved a stalemate.
We would mop the floor with them and they knew it.
Iran absolutely does not want to be our enemy in a war.
