If Scotland and Catalonia ever become independent countries, it will only be because the UK and Spain permit it. All states have an interest in stability, so it is hard to imagine that, in the absence of widespread, grave, and undeniable human rights violations, other states would recognize a region that, after being part of a state for many centuries, declared itself independent without the acquiescence of the country from which it secedes.
只有得到英国和西班牙的许可，苏格兰和加泰罗尼亚才能真正成为独立国家。稳定符合所有国家的利益，因此很难想象在没有严重、大范围、无可否认的侵犯人权行为的情况下，其他国家能够承认一个几百年来一直属于某国领土的地区在未征得被分离国同意的情况下宣布独立主张。
