Seems like the recipe for independence, and agreed upon borders, and thus whatever interpretation of the second amendment one wants involves exactly choosing nuclear bombs, and managing to stockpile enough of them before being bombed oneself. At least at the nation state scale. Sealand certainly resorted to arms at several points in it's history.
The second amendment only applies to the United States -- it's totally normal to have one set of rights for citizens and another set for the government itself.
