Any clout or influence the UK has, Scotland will have at best 10% of that, we have no credit history, no armed forces, no currency established, membership approved for nothing, we will be at the doors asking to get in, and accepting any criteria / conditions that are flung our way (% of oil revenue, greater control from Brussels, schengan, etc etc), NATO, EU, and UK will not need Scotland after independance but Scotland will need them, so they will set the conditions and we will need to fall in line
