I beg to differ. Putin's law school thesis was "The Most Favored Nation Trading Principle in International Law." Granted, that may be slightly better than "Tentative Study of Agricultural Marketization", but both are only theses, not a full book: "The Art of the Deal."

The difference is also clear in their propaganda:
