There is a possibility of engagement and clashes, but Russian troop numbers so far don’t seem enough for a full on invasion and certainly not enough to occupy and control a country the size of Ukraine.
Today the rouble and Russian stock market went into free fall which isn’t helping the Russian rationale for invasion (not that they have much of one anyway).
Finland is beefing up security on its border and if the US puts troops into the NATO Baltic states then this Russian idea of trying to force withdrawal of NATO troops/bases is not going well.
Today the USS Harry S Truman aircraft carrier, along with its strike group and air wing, joined patrolling activities across the Mediterranean Sea, the first time since the cold war that a full US carrier group has come under Nato command and there is a joint exercise in two weeks with US, French and Italian carrier groups.
Other European countries are also contributing ships and the only country on the sidelines is Germany which has a strong pacifist and appeasement sentiment.
No idea where Putin is going with all this, but if it was to make NATO or Europe back off then it isn’t working.
