Saudis have enough high tech toys and foreign mercenaries to deal with this without USA holding their hand. Afterall, they undeniably proved their quality in Yemen.
Yes they did.
Somehow though, I'm not impressed with unrestrained civilian casualties so the Saudis can improve their aim.
Iran needs the War to start before November 4th 2020.
Ideally, yes.
A war between Iran and the Saudi/Israel alliance is all but inevitable at this point, and the best case for Iran is that the US is only neutral in SA/Israel's favor. More realistically, the US would provide political cover, ramp up economic attacks on Iran, provide SA/Israel with a nigh limitless ability to resupply, provide C4I assistance, unless the NSA/Cyber Command to show the Russians and Chinese how to really do cyberwarfare, and have the USAF and USN striking high value targets inside Iran/supporting the alliance.
I disagree.
Trump, if he wants to get involved at all, will not take us to war, because that is not in the US's best interest. Nor is it in his best interest as President. What IS in his interest is to sell weapon systems to Israel and Saudi Arabia. It is also in his interest to defend Israel, thanks to politics within the GOP. And that can be done in various ways without going to war. The Neo-Cons and Zionists might scream, but they don't have the pull and they know a war will cost Trump his position.
What Trump can do, with minimal damage to himself, is to instead give intelligence, material support, and strategic guidance to SA and Israel. Maybe even use of American bases. First, Trump puts the full pressure of SWIFT upon Iran. Then he encourages Israel to take out Kharg Island.

Take Kharg Island out and Iran can say goodbye to 98% of its crude oil exports. The damage that will do to the Iranian war machine, in addition to what Trump can provide without having any US owned military assets firing a single shot is more than enough to put Iran's victory into doubt.
SA and Israel aren't really ready for war with Iran today, and the US is not interested in an ME war until after the elections. Iran's best chance is to get the war started now, prevent a quick alliance victory, and let the political cost of said war get Trump out of the Whitehouse; and then sue for peace with the newly elected Democrat. The risk Iran is taking is that Trump will decide that his best play is to go all in and will unleash the US military with the loosest of ROE's inside Iran and orders to render harmless/destroy the nation of Iran and its ability to do anything as rapidly, efficiently, and safely as the US military can manage (with no attention paid to Iranian civilian casualties).
I say no.
The fact that Bolton is no longer part of the Trump Administration tells me that Trump is not interested in a prolonged conflict with Iran. The most he might do is make a few military strikes, like he did before. Americans really don't care too much if we fire missiles at people. What we care about is an expensive war in which human lives are sacrificed without any apparent gain for the US.
There is no rational that I can find for why Trump will want to take the bait.
