SS security is only for 9 years, IIRC.
As an American, especially a former POTUS, there is no chance he will ever be UN head, as P5 members are barred from that position.
The next SecGen will likely be Muslim.
zer0 will be lucky of he gets any speaking engagements at all. He may spend time writing his memoirs while Michelle will rake it in with diet and fashion and parenting books.
Thanks for informing me about the rule against P-5 Security Council members being SecGen of the UN.
Nevertheless, even though that position isn’t available, Obama will still promote himself as a spokesperson for the world. And, he will hammer on the US as one of the world’s greatest problems. That’s a sad forecast for a President, alas.
