How did ottoman control of the dardanelles and German submarine warfare in the Atlantic have a similar impact on ww2?

Both Ottoman control of the Dardanelles during World War I and German submarine warfare in the Atlantic during World War II significantly influenced the strategic dynamics of their respective conflicts by controlling vital maritime routes. The Dardanelles' control restricted Allied access to the Black Sea, impacting supply lines and military operations in Eastern Europe, while German U-boats targeted Allied shipping, threatening supply chains and forcing changes in naval strategies. In both cases, the control of these waterways hindered the movement of resources and troops, contributing to the broader challenges faced by the opposing forces. Ultimately, both strategies showcased the importance of naval power in determining the outcomes of the wars.
