In 1914 what was a way that some countries thought they could protect themselves against foreign attacks?

In 1914, many countries believed that forming military alliances was a key strategy to protect themselves against foreign attacks. These alliances were intended to create a balance of power, where nations could rely on each other for support in case of conflict. For example, the Triple Entente included France, Russia, and Britain, while the Triple Alliance comprised Germany, Austria-Hungary, and Italy. This network of alliances, however, ultimately contributed to the escalation of tensions that led to World War I.
