Well, maybe we could roll the dice and see what a Palestinian State would buy us? Spoiler alert: Nothing. But it would benefit Iran no end.
I interpret the “support” for PA recognition by France and the UK as primarily an effort to appease their restive Muslim population.
Reminder:
Palestinians are Sunni. Iran is Shiite. They have hated each other for far longer than either has hated Israel.
Lebanon and Hezbollah are Shiite. Palestine and Hamas are Sunni. You want to find support for Hamas, look for Sunni sources.
As was true of 9/11. The Saudis. They escape blame and attention by exporting 2-3X more oil than Iran.
