"It began to dawn on me that perhaps my country needed me more at home than overseas"

This quote by Larry David speaks with the suggestion of nationalism as well as the value of serving one's nation. It suggests that occasionally, the very best method to offer one's country is not always via military service or other types of overseas service, yet by remaining at residence and also contributing to the nation in other means. This might indicate anything from offering in the neighborhood, to working in a work that helps to improve the lives of others, to simply being an energetic and engaged person. By acknowledging the importance of staying at residence as well as contributing to his nation in other methods, Larry David is showing his dedication to his country and his determination to serve it any way he can.
