Are you surprised the Saudis are getting a bit twitchy, when on top of all that the Saudi Aramco stuff goes down?
Now let's be clear: I do not support the idea of a war Iran. That is actually what Iran and its allies want (think about the Obama/Kerry cartel that have continued to speak to and meet with them since Trump has gone into office). Iran can be dealt with by other means.
They'll keep trying to provoke Trump and the Saudi who might poke back a tad, but don't expect anything drastic. It's the Iranians that are getting desperate, not the other way around. Trump and the Saudis and keep up the pressure and wait them out. Iran's economy is an absolute basket case and while they keep spunking all their $$$ on paramilitary ops across the ME (including the Obama pallets of cash), the situation of ordinary Iranians is only going to further deteriorate. Expect more civil unrest.
