1995年2月、国防次官補として通称「ナイ・イニシアティヴ」と呼ばれる「東アジア戦略報告(EASR)」を作成。東アジアに約10万の在外米軍を維持するなど、冷戦後のアメリカの極東安保構想を示した。この構想は1997年の日米防衛協力のための指針(いわゆる新ガイドライン)における日米同盟再定義とつながっていき、第一期においてはまとまった東アジア政策を持たず、日米経済関係を巡って緊張しがちだったクリントン政権が再び東アジアへの関与を強め、対日関係を重視していく重要な契機となった。2000年には対日外交の指針としてリチャード・アーミテージらと超党派で作成した政策提言報告「アーミテージ・リポート」(正式名称:INSS Special Report "The United States and Japan: Advancing Toward a Mature Partnership")を作成、2007年2月には、政策シンクタンク戦略国際問題研究所(CSIS)においてアーミテージと連名で再度超党派による政策提言報告「第二次アーミテージ・レポート」(正式名称:"The U.S.-Japan Alliance: Getting Asia Right through 2020")を作成・発表し、日米同盟を英米同盟のような緊密な関係へと変化させ、東アジア地域の中で台頭する中国を穏健な形で秩序の中に取り込むインセンティブとすることなどを提言している。
