What happens tomorrow if Russia shoots missiles into Finland and Sweden before the Alliance is signed?
I bet that would accelerate the two nations' accession into NATO. The war won't widen immediately, but the Russians will now have fewer munitions which are needed in Ukraine, and have an angry northern frontier that will need guarding in Putin's mind. The Baltic will almost certainly be closed to Russian ships trying to exit the Skaggerak, as well.
