Robert L. Goldich thinks so:
What would be the foreign policy of an independent Scotland…? Would it join NATO? How much, if at all, would it cooperate with the armed forces of a truncated United Kingdom? With the armed forces of other Western democracies, including, but not limited to, those of the United States? Would it cooperate with the British intelligence services in the maintenance of internal security against terrorism in the British Isles? Would it cooperate with other countries’ intelligence services, including those of the United States? Would it look more leniently on the presence of embassies and diplomatic representatives, and their activities, from anti-American and anti-Western states such as North Korea, Iran, and Venezuela?
Mr. [Alex] Salmond and his Scottish Nationalist Party, and the dominant political culture in Scotland, is quite far to the Left, for a variety of internal reasons that don’t matter here. This doesn’t augur well for a positive answer to any of these questions. It suggests that we have to consider that, a la the Republic of Ireland, Scotland might well be aggressively neutral, and avoid involvement all kinds of Euro-Atlantic collective security agreements that have been so important in maintaining European stability since 1945.
