They officially announced they will not negotiate until Trumps out of office. There's no point doing so he just keeps lying about talks and they have no incentive to participate, the Strait is closed, if you want to get through you have to pay Iran, so they're going to stay like this until Trump is gone.
IT has been clear for awhile but they just made it REALLY clear, they are actively trying to impact the midterms by screwing Trump over.
We're weeks away from a global oil crisis, the only ways for him to "get out of it" would to either completely capitulate, or snap and nuke them, either of which would hurt the GOP in the midterms.
