idk about 300 billion, but the Gulf States have already, and rather silently, unfrozen north of 10 billion in assets (https://www.aljazeera.com/news/2026/6/12/uae-to-unlock-froze...)

which is of course the real kicker, The Gulf states are going to pay for the adventure and deal with an emboldened Iran and their damaged economies and infrastructure. Having US bases in the region has turned from a security guarantee into a disaster, the implications of this are pretty obvious.
