Let's talk about Duginism
Iran wants to decouple America from Israel.
That's the entire “chess game” now.
Iran knows it can't take both nations at the same time – so if it can cause disarray, distrust, and disloyalty amongst the two (particularly their right-wing, pro-military factions) then you can hope for a far more isolated Israel in the near future.
This pursuit is Iran's current gameplan, both rhetorically and through the means of propaganda. You can see it all around you right now, and unfortunately, many people are falling for it. Hook, line, and sinker.
