I see this as significant. Yes, Iran is the enemy of both bin Salman and Trump, but this has more bearing on beating deep state globalist enemies. His domestic enemies can deploy court orders, congressional sabotages, and special prosecutors to tie down Trump, but they cannot stop him from launching offensive via a foreign country. It is not just globalists who can play a global game. Trump can, too.
What's happening in Hollywood, while not coming from Trump, will have a devastating effect on donations to the democrat party.
Sessions and others have closed slush funds in the government used to fund left wing organizations.
And now the Saudis who fund the deep state are being replaced by Saudis who don't. This as much as anything is the end of the Bush/Clinton/Obama era.
And in all of this, his supporters have not been negatively affected at all. By the time the election rolls around, the democrat party will be bankrupt and unable to run nationally, and Trump will appear to have done nothing.
