The Saudis waited for instruction from Trump. He said wait, I have a possible meeting with Ruhani. Ruhani declined the meeting in this UN summit.
Now that Trump's hope is over, the signal has been sent "you can go for war". Which raises the big question -- actually who goes to war?
Saudis want "the world" to go to war. "It's an attack on the world."
USA wants the Saudis to go to war. "It's your problem."
And Israel wants the USA to go to war.
We need to solve this problem first, if we want to see war :V
Early this year MbS asked French war analysts on whether a Normandy like coastal invasion by Saudi forces on Iran was possible. And the analysts laughed it off, calling it mad. Now you don't need any analyst to realize it after Aramco attack.
But won't we see any war? We shall, just wait for it.
