What does Gulliver do to assist in the defense against Blefuscu?

In "Gulliver's Travels," Gulliver plays a significant role in the conflict between Lilliput and Blefuscu. When it comes to helping defend against Blefuscu, Gulliver's primary contribution is promising protection. This promise is crucial because it reassures the Lilliputians of their safety and provides a sense of security in the face of potential attack. His stature and strength as a giant are instrumental in scaring off potential aggressors, which serves as a significant deterrent for the enemy.

The other options suggest different levels of involvement in military strategy or action. Leading the army, providing military tactics, or building ships are all actions that could imply a more direct engagement in warfare. However, the most pivotal and immediate contribution Gulliver makes is in offering his assurance of protection, which reflects his willingness to support the Lilliputians without directly engaging in combat. This act reinforces the themes of cooperation and the absurdity of war present in the narrative.
