Okay, it is pretty clear that there is no stab coming from US, as he seems fully invested in driving the French out of the Mediterranean.
Kiritsugu can fuck over US in one too many ways, and by using the armies in Tyrolia, Trieste, Vienna, Budapest, and one of either Bohemia or Silesia, he can ensure Rumania and Sevastopol for himself this year. Which will clearly set himself up for a Solo this game. But I think he is too good a chap to do that, so no breathing space for you Mr. Walrein!
Dr. Awesome is probably drinking his sorrows over a barrel of wine and waiting to be exiled into an island near Brittany.
Walrein is having fun in the North as he is going to get StP unopposed, and can probably setup a final stand against this Buggernaut alliance.
All in all, throwing peanuts in a gallery is more fun than being in the thick of battle. Have fun guys! ^_^
