I imagine that most of the Western leaders are breathing a huge sigh of relief this morning. The two annexed regions were already under Russian control and Tanks moving in there is the least that could have happened. Ineffectual sanctions to show that they are doing something but no requirement to make much in the way of meaningful, as in military actions, no 24 hour TV of Ukrainians fighting and dying whilst refugees pour into the east of the EU. If Putin had actually invaded Ukraine held Ukraine they might have actually had to do something.
