Generally speaking powers defend together. However in G40 there are powers that start off neutral (Russia and USA) or not at war with each other (like Japan and UK/France). You could have a case at sea when you attack a sz with units from multiple powers, and can ignore the units that belong to a power that you aren’t yet at war with.
Yukon territory question…
-
Is the Yukon territory inaccessible? Meaning, you can’t put units there? I’m trying to move an American AA gun from Alberta to Yukon in TripleA and it’s not letting me. Does that also mean that a Japanese tank can’t blitz from Alaska to Alberta? Thanks!

The territory was deemed redundant and made inaccessible in second edition. You can still just blitz through British Colombia just fine.

yukon and bc were combined into western canada.
