If you watched his address to Congress, you’ll also recall that he called Kerry & 0vomit his friends, or words to that effect. I believe he is playing the game as required to maintain appearances.
BiBi believes he has Americans support...so he will always frame his words as “friends” because he does have them here..and many of them. Including our Congress.
It’s very difficult in diplomacy for every nation leader because nobody likes dealing with Obama...they know he’s wacked when it comes to Foreign Affairs and is making a mess of the World..
