Some historians believe that this is partly because Switzerland maintained a high degree of military vigilance and partly because Switzerland made a huge compromise with Hitler at that time.

In p>1815, the countries that won the Napoleonic Wars held a peace conference in Vienna, and the Declaration of the Vienna Conference finally declared Switzerland a permanent neutral country in Europe. After the Battle of gaeta in 186, Swiss mercenaries bid farewell to the battlefield completely. This federal country, founded by military force, began to advocate peace and neutrality.

since then, Belgium and Luxembourg have also sought the status of "permanent neutral countries", and they have successively become permanent neutral countries according to the London Agreement of 1831 and the London Agreement of 1867 respectively. However, Belgium and Luxembourg were invaded by the Germans in World War I, and their permanent neutral status was destroyed, which was abolished by the Treaty of Versailles in 1919.

However, Switzerland maintained its status as a "permanent neutral country" in World War I.. The International Red Cross in Geneva played a very important role in humanitarian relief, which made countries' influence on Switzerland very recognized. Therefore, after World War I, the Versailles-Washington system reconfirmed Switzerland's permanent neutral status, and the League of Nations was headquartered in Switzerland.
