Norway is very difficult to take back if lost. The Allies could take it and keep it.
But 2 rtrn, and ac g1, then it will be hard for Brits to hold norway.
in 1941 norway finnland is a "worse" place for uk/usa to funnel troops to due to the additional distance to go towards germany,. also since trnīs no longer works as cover, itīs harder to keep a fleeet alive for uk/usa.
So itītīs viable but not neccesary since german ic works better, and i would agree a Ic in france would work better, but i would rather put one in balkans thought, sió germany can put so e troops into africa if needed.
