Now that the new interim President of Brazil is of Lebanese origin, The Washington Post surveys the success of Latin American politicians pf Arab origin.
Which reminds me of a brilliant remark I saw somewhere on social media, though I must apologize to the author for forgetting who said it: Brazil now has a Lebanese President, while Lebanon still doesn't.
The Lebanese Presidency has been vacant since 2014.
Update: a commenter credits Karl Sharro and it certainly sounds like him, though I can't locate the original.
Update II: Apparently a lot of people had the same thought.
