Russia gets a phonecall from dad telling it to come home and sleep. Luckily, beach-jockey USA waltzes onto the scene just in time to keep this triparty going.
The US navy is a lot bigger than I remember, large enough to tip the balance at sea very much in our favour. They have no army whatsoever (one company of marines) and nothing in their build que.
Fortunately I have been able to start researching key technologies already, so their preparedness is not completely rock bottom. It’s going to take a little bit, but soon all of those lovely resources (acting as the motor of the US economy starting to spin with the war entry and digging them out of depression) will grow to full productivity. In five of my turns their base war economy will increase by 120 (4*30, mines) + 100 (5*20, oil). That’s if they are str 10 at least, not sure if they are. Could be 8? Nonetheless a substantial increase.

Their industry modifier is 100% base, so any industry tech will add 15% on top of their total production.
In addition, they have a major capital. That means all of Canadas resources will grow to full productivity as well.
Having to build their fighting strength from scratch means their first army will probably land in France sometime this late autumn.
What they can do, however, is start bending their economical and political might to the ententes cause. Our first target is Holland, as taking them out of the central powers camp will cause recurring NM damage to Germany. With only 9 chits to contest, there is nothing KZ can do except slow me down. He’s created a buffer in their leaning with his own diplomacy, but they will withdraw.
Scouting airships find no sign of the Kriegsmarine around the North Channel, and we have seen no sign of them around the shetlands or Orkneys. Scouting submarines find nothing near the east-coast of Scotland.
One mine has detonated on the near blockade line though, and the other Submarine screening the approach find a large concentration of ships.
Two ships are at anchor in the west-side ports. The way is also clear into the Baltics.

I debate this for some time. I would very much like to place some mines next to those ports, but I dont think losing a destroyer to do so is worth it. I’m not sure how much of the Kriegsmarine is in that ball up there, but given the complete lack of presence elsewhere I have to assume the worst and say “Probably all of it”. Engaging it in that form instead of the piecemeal, fleeing mess I had hoped for will only lead to huge damage to my ships as well, especially considering the tech advantage the Germans still have.
Instead I leave some subscreens and withdraw, sending as many ships to port as I can.
Several light cruisers and a French destroyer takes a lot of damage clearing the mines off the raiding squares, but at least now the English ports - and more importantly their trade convoys, can start to recover.
I had my mind on a more defensive posture in Germany, but spotted an opportunity too good to pass up.

For some reason KZ left an airship next to a corps, with nothing else to screen his guns. I strike through and destroy them easily, thanks again to mobility tech. I may well lose those two forward corps, but it’s definitely worth it to get rid of a German gun for most of the summer.
With the collapse of Russia things are probably going to get rough here for a while. I debated attacking Belgium and Holland for a while (and have been pondering whether to do it with the US entry since I went for the US strategy) but decided against it. My position is good as it is, and I dont want to hurt my NM any more than necessary. The UK cant really handle it, and it’s stupid to throw away a good NM advantage when you’re looking at fighting on the defensive for a while.
Greece is quiet as the Greeks deploy their guns. The transport is sunk by the destroyer in the Mediterranean, and the Austrian torpedo boat found and damaged by the Pre-dread.
5 corps worth of French and British troops transfer from Britain to France. I keep several cavalry corps in the UK, since I will have to avoid the puddle to the east for a bit. A japanese destroyer appeared at Gibraltar, I cant remember seeing the event for this.
I missed a mine somewhere I think... or a ship. Something is still raiding me at least. Going to have to search next turn.
