Right now, every country in the ICW except for Wizarding Britain sat NEWTs that were up to ICW standards. This meant that, at worst, every country at the ICW conference except for Wizarding Britain would vote for the Australia-USA resolution, and this vote would exceed 90 percent. Then either Wizarding Britain would be forced to change its laws (for which, Albus would be blamed), or Wizarding Britain would leave the ICW (and Albus would lose his Supreme Mugwump position).
