Téma: Thesis on American-German relationships in post cold war period

I want to know are there any english- or german language phd thesis on post-cold war era development of american-german relationships? Where to search for at least the abstracts or even topics of such thesis in Germany as well as in USA? Additionally I am interested could it be prospective topic and are there enough research on such bilateral relationships along with documents, declarations, statements, interviews to build the source basis of such dissertation?

I didn't find the right solution from the internet.
