Kurtzer joined the staff of Secretary of State James Baker. He helped write Baker's noteworthy speech to American Israel Public Affairs Committee in May 1989. The speech was originally drafted by Harvey Sicherman, who used uncontroversial pro-Israel language in his text. Kurtzer's revisions included an attention-getting line that encouraged Israel and its supporters to abandon the Greater Israel idea. According to Aaron David Miller, he and Kurtzer wrote short memos for Baker on issues at hand, rather than longer, strategic papers.
