This is a case that affects Sweden´s neutrality policy. The study enters the subject of the Swedish solidarity declaration´s impact on Swedish security policy. Sweden has for decades been recognized as the land that stands neutral whenever there is a conflict or a war. Sweden was neutral during the east – west power struggle under the 1950s right after the Cold war era ended. Yet in more recent years a transformation has been recognizable from neutrality policy to solidarity policy. The global transformation has led to new and more spreading threats like terrorism. This has led to nations who have one thing in common: peace and stability. Alliances are not only formed right after wars any more like they used to be, but nations are willingly seeking for an international community where they can coexist between and amongst each other. The presented empirical material comes from official documents from the Swedish government, research done by high trusted writers and researchers. The method is to represent a historical overview of the main subjects in the issue. Most of the material to the raw facts is mainly from Neutralitetens uppgång och fall – Eller den gemensamma säkerhetens historia and Trovärdig solidaritet? – Försvaret och solidaritetsförklaringen.  The studies theory originates from The English school theory about nations will to coexist with each other and the fundamental factors about why.
