In the YouTube video you link to Biden mumbles that "Russia has bitten off some real problems they are going to have trouble chewing on" and then goes on to say that Russia should be providing for people in Libya, I mean Russia, I mean Syria. Whatever, man. Wanna do some pushups?

So Russia has bitten off "some real problems" and Russia is supposed to provide for the Syrian people we (the US) are bombing while simultaneously we (the US) are allowing ISIS to hold Idlib province in Syria and the US is ALSO illegally occupying 1/3 of Syria, the one-third where Syrian oil fields and wheat fields are while ALSO Simultaneously we (the US and Israel) are sanctioning and bombing Syria and anyone (i.e. Iran) trying to help Syria.

Yeah, those Russian certainly have bitten something off. They've bitten off a piece of US hegemony, and the US is not having any of that!
