Scott Ritter and Jeffrey Sachs differ on a possible Iranian War

I watched Scott Ritter, a former active member of the US military (not sure about his current status), and he says there will be no war on Iran: the US military commanders, the generals and admirals, know that Iran has weapons that can destroy:

1) All of the Great Armada(s) the US are sending to threaten Iran in the hope that Iran will surrender and disarm;

2) All of the US military bases within 1,000 miles of Iran;

3) All the oil producing areas in the countries hosting those US bases;

4) Most of Israel;

and Iran can close the Strait of Hormuz, which, added to the destruction of oil producing facilities, will block the world from about 25% of all the traded oil that travels by ship from producer to market and raise the price of a barrel of oil to at least $700.

So there is no way they will allow any US attack on Iran.

I then watched Prof. Jeffrey Sachs, who thinks Trump is an idiot who might start the war without thinking, and who would definitely start the war if ordered to do so by his Zionist owners.

There seems to be a disconnect here, but they were on separately, and Prof Sachs, who came on second, did not respond to Ritter's assurance that a US or Israeli war on Iran is impossible, but figures one is almost certain to happen, with disastrous results.
