Would Norway have opposed a British invasion as well?
Short answerResistance was possible, but a British claim to enforce neutrality without imposing a replacement government might have divided opinion and gained support from the king.
NotesNorwegian resistance would remain a problem for any British intervention. The proposed political distinction is that Britain could present its forces as enforcing neutrality after the Altmark incident, without installing a Quisling government. Publicizing the government's failure to enforce neutrality might also divide Norwegian opinion. Support from the king is suggested as a possibility if the deployment remained a protective military presence. These are possible responses within the counterfactual, with no assurance that Norwegian consent would follow.
