Bhagwati nailed it. Susan Schwab is being a maximalist:

Those countries’ chief antagonist was the United States, which was represented by Susan C. Schwab, recently appointed U.S. trade representative. Schwab repeatedly maintained that the Doha round, named for the Qatari capital where the WTO started it, must achieve an “ambitious outcome.” That would mean tariff cuts that are deep enough, and with few enough exceptions for special products, to generate significant new trade around the world, including in big developing markets such as India, Brazil, Indonesia and South Africa.

She did not dispute that the United States had emerged as the outlier in the talks, in opposition to most of the WTO membership. “Isn’t that what leadership is about?” she said in an interview. She said she was “dismayed with the number of countries that just seem willing to settle for some least-common-denominator solution.” [WaPo]
