The European fascist dictators of the 1930'swere all willing to expand borders by using what?

The European fascist dictators of the 1930s were willing to expand their borders primarily through aggressive military invasion and territorial expansion. They justified their actions with ideologies of nationalism and the belief in the superiority of their nations, often seeking to reclaim or annex lands they claimed were historically or ethnically linked to their countries. This expansionist ambition was exemplified by Hitler's annexation of Austria and the Sudetenland, Mussolini's invasion of Ethiopia, and Franco's support for fascist movements in neighboring countries. Such actions ultimately contributed to the outbreak of World War II.
