I said if the clerics are eliminated there will be a huge power vacuum.

True.

If the Iranian people want freedom they'll have to fight for it.

A LOT of "IFS" for a very unruly fragmented country of 90 million that has never western Democracy.

And "fighting for their freedom" makes the disorder following a regime collapse sound like a linear march toward civic order. Far more likely you have utter chaos. Iraq, a much smaller country, collapsed in inter group conflicts and required occupation. Iran will be several times worse.

The US shouldn't be involved in that and certainly not in a war with Iran or regime change.

And look at the track record of the US in Iraq, once again. It'll be exactly the same deal, just scaled massively. This will NOT be clean or surgical. It's madness.

I've read that a war with Iran could destroy the US. I think that is close to correct.
