I admit I am stupid but I don’t get it
No, you’re not stupid. You are smart enough to read FR!
Anyhow, basically it’s just Putin telling our brave POTUS to hush up as he’s totally uninterested in listening to Obama’s blabber about how he should handle Ukraine.
Oh, and Obaby is so far out of his league thinking he can ever relate to Putin. Or any other world leader with experience for that matter. To deal with Putin he’d need to do so man to man which is unfamiliar territory to Obama (unless you consider his interaction with Moochelle...)
