IMHO it would not have been necessary for Norway to choose the side. If only the PM Nygaardsvold had given in in 1937 and allowed new funds for rearming then instead in next year and if Norwegians had defended more vigorously its neutrality in1939 - 40 and if the mobilization had been allowed on 5 April, when the C-in-C demanded it Norwegians would have a reasonable chance maybe even avoid the invasion or defeat it if it had gone ahead.
