Why does Bernies career amount to him giving the correct answer, and then some deeper party goon gets the headlines, usually right before they use the moment to become a complete lobbyist dick sucking asshat?
Actually it's not wavering as much as a display of Obama's pragmatism. He doesn't have to play with geopolitics the way Biden does, and would admit it.
His comments didn't "surface". They were made openly.
And nothing he said was opposed to Biden. He just said there's a lot more context than people realize and innocents who are being hurt. Biden himself has called for a more tactical approach than what they've done.
This is just the news trying to spice up Democratic politics because it's not as interesting as the Republican politics.

Edit: Biden is making moves to allow him to fund Israel completely black box. As if Pentagon black box isn't enough, he wants President to Israel, full closed door blackbox.
