Imo, such a war would probably be called the Second Russo-Japanese War.
Must be obscure, cant find anything online. It seems similar to the Trent Affair. If 'war' DID happen, it would probably end after a few naval skirmishes in Alaska, with the Brits having to pay reparation's (unless it escalates even further, that's a story for later.)
This would have been interesting to see just for the possibility of having a Norwegian Greenland, instead.
I wouldn't expect this as leading to a Norwegian Greenland; second option as listed below
might.

I just finished reading about the Agadir Crisis in "The Sleepwalkers" by Christopher Clark and my impression is that neither the German nor the French government actually wanted war. While the anti-German hawks in the French foreign ministry initiated the crisis, the French premier Caillaux soon instructed the German ambassador Cambon to seek a diplomatic solution, circumventing his cabinet. The Germans did send a warship to Morocco but they only planned a symbolic protest and the fact that the ship was underequipped reinforces the argument. The impression of an imminent war is more a result of sensational headlines from the nationalist press in both countries.
If you want a wider war in South America in the mid-late 20th century then you also can include a Chile-Peru war. The Chilean Armed Forces in the late 1970s had anticipated a preemptive strike against Peru.
Create some extra tension during the South American Dreadnought race, and you get a pre-WW1 ironclad battleship fight.
I do love the story that, as the Panther was sent to Agadir on the basis of protecting German civilians, they had better get a civilian there pronto. Apparently the Panther's crew realised he was not a native on the beach as he had his hands in his pockets.
