This dosent change jack shit. UN memberships have to be approved by all the perminent members of the security council and the US is a perminent member of said council. And in the UN the US always does what Israel tells them to.

If I remember correctly last year there was a vote on palistine becoming a member and the only countires that voted no was the US and Israel but palistine is still not a member because Israel told the US to block it.
