Why bother? What use does Britain have for Ireland... All it has ever done is cause us [censored] problems...
Oh and I do not think that Britain would have a problem after the war, with our greatest asset at this time being our Navy we would likely even after the 2 hour war have a huge navy.
Ships float, they can be as heavy as they bloody want to be, they could make NUCLEAR FUSION powered ships, the fact that it is possible to have NUCLEAR FISSION... You could have some MEGA battleships with that power...
Not to mention they are active in water, Fission uses hydrogen, water... + electric current = hydrogen... Unlimted fuel?
Britain I believe would cope because;
She has already had experience with total war and survived.
Her sea power is almost impossible and EXTREAMLY expensive to destroy with nuclear missles.
She could lose her army in the Resource war, but she would still have her navy and that would stop a landing.
After the bombs the majority of her land would be wasteland but she would still have a huge navy just floating around.
Which begs the question why they havent show up in America... Maybe they were clever, Aftrica wouldn't have been bombed...
Maybe Britain after the war sailed her huge fleet of warships to Africa and now there is a single Super Power rebuilding her Empire with the Non Radiated parts of the world...
Ooooo I like this idea....
Does Britain still own all her Colonies?
If so then she would have a few small battle groups of Warships based at her colonies during the war to stop them being siezed and to keep a steady supply of Collonial troops.
Britain at the time in which the time line breaks was also producing the most Warships she ever has, and we understand that the timeline breaks because after WWII the production of Armerments does not slow down, it increases.... She would build more ships.
I belive that most of the Chinese and American Fleets would get churned up in the northern hemersphere, in open water.
However if british are at war in europe, they have a nice closed water enviroment of the Mederterenian, on which they have a WWII Plane and Ship repair yard of Malta, and the only entrance to the Med for the Russians is the small water way next to Constantinopal.
Because there would be no Russian ships they would have complete sea supperiority and be able to just shell from the shore line all around Russia, giving significant advantage and meaning that her ships were so far appart they would be impossible to nuke all of them.
Thats just a few ideas ide like to contribute.
OMG the Commonwealth from F3 should be the British Expoditionary Forces, This would ACTUALY mean Bethesda could add a realistic new faction to F4...
-Just a funny idea that hit me...
