Lets Get Real:
This will WARN Putin that any attack on NATO Countries will LEAD to WW3, the problem is not that, Putin is not that far gone, well one hopes, the problem is the Ukraine, one can expect that Putin will invade after the West gives its formal NO to Russian demands, that the Ukraine never joins NATO and that NATO troops are removed from East Europe States in NATO. The Russian firepower, land and sea is for a quick kill, that is brutal but that what Putin wants, he wants to absorb the Ukraine back in to the Russia, he wants the OLD USSR back, for that to work Putin will have to go after the BALTIC STATES and Poland. The Biden Oval does not have the guts to send US troops in to Ukraine, that would really STOP PUTIN in his tracks, what he can do is make so that any Ukraine insurgence is supported by the West, Biden can make Russia bleed, as Reagan did in supporting the insurgence in Afghanistan after 1981. Thus there are more diplomacy, the UK Defence Secretary will visit Moscow, one hopes that the Russians have the courtesy not to invade the Ukraine if the Defence Minister is in town. Thus after the formal reply from the West and the departure of the UK Minister one can expect a quick strike, the question is will the Ukraine fight, one saw what happened in Afghanistan, one's hopes are really with the Ukraine Army and people.
