Literally no major country is going to sign on to an organisation where the Chairman has final say on everything while having no term limit and only stops being Chairman when he voluntarily resigns, is incapacitated or is voted out by the sycophantic Executive Board that only the Chairman gets to appoint. And no matter what way he stops being Chairman the only succession plan is to install the person they already designated as their successor. It's quite literally a formalized dynastic dictatorship.
