Is the argument limited to naval battles?

Does the discussion cover only naval battles?

No. Land, air, political, and logistical decisions are included when they shape naval outcomes or otherwise show a direct First World War influence.

A viewer asks whether the title refers only to naval battles. It does not, because land campaigns and other military decisions can shape the conditions under which naval battles occur. The answer establishes a combined historical scope rather than treating sea power as an isolated system. It also reinforces the video's causal test: a decision belongs when First World War experience can be connected directly to a Second World War consequence, regardless of service boundary.
