The worst-case scenario is now a possible one: European troops fighting off an invasion largely alone.
It’s by no means clear the Europeans would succeed. Romanian and other European officials at the exercise in Cincu, about 260 kilometers (162 miles) north of Bucharest by road, voiced concerns about how long it would take for NATO allies to make it to the front.
French four-star General Philippe de Montenon said he’s confident Europe could prevail, even without the US on side. “The direction of history is a progressive disengagement of the United States from the European continent,” he said.
Why would the navy be relevant? The war is about controlling the area that cannot be reached by ships.
Nuclear submarine are part of the navy. So it’s an important asset, especially in the deterrence and strike game. We have good payload capabilities (all proportion garded) thanks to the navy. And projection force from our aircraft carrier is also a good asset.
If none of their ports work, I’d guess it would affect their war effort considerably. It also means stable supply lines by water and no worries about naval movements.
