And just to hammer it home: the US dragged its ‘allies’ into an unwinnable war while ignoring their strong warnings and objections (so much for shared interests…). 

Their defense commitments then proved questionable because the US couldn’t prevent the Iranians from dealing massive damage to oil, gas and military infrastructure all across the region. 

They then escalated the war, causing the Houthi’s to block the Bab al-Mandab Strait which dragged the Saudi’s even further into this war.

And now that the war is finally nearing its conclusion, the US has depleted its intercepter stockpiles, has lost a lot of its military infrastructure in the region, has pulled many of its air assets from the region and is likely going to accept de facto Iranian control over the Strait of Hormuz, because they have no leverage whatsoever.

This leaves the Saudi’s reeling from the massive political and economic damage from the war, having to deter a stronger and emboldened Iran, while still being embroiled in a guerilla war with the Houthi’s, being largely unable to defend itself from drone and missile attacks, while losing its primary security guarantor because they just suffered a humiliating strategic defeat.

Oh, and the Iranians are now 100% guaranteed to try and develop nuclear weapons in the next few years and Russia is probably desperate enough to lend them a hand.
