Biden is saying that the missile didn't originate in Russia, which implies that he knows a lot more about it than he's saying. The BBC has just said that there was a AWACS in the air at the time tracking the latest attacks so there's reason to think he does.
NATO is clearly talking it down and it's fairly clear that targeting a farm in a NATO country isn't likely to be a deliberate Russian tactic but Poland is asking for an Article 4 meeting. Ukraine is asking for NATO air support which they won't get but they may get more equipment as a result.

Faith is the denial of observation so that Belief can be preserved."
