How a successful Dardanelles campaign could matter

Would a successful Dardanelles campaign significantly change the course of World War I?

A single decisive transformation is unlikely, but the campaign's cumulative effects could become one of the pressures that materially alter the war.

Success in the Dardanelles would not automatically decide the war. It could still add important cumulative pressure, one of many changes whose combined effect might become significant even if the immediate result remained limited.
