I’m merely a student, while Grant Aldonas was US undersecretary of commerce for international trade from 2001-05, but he’s crazy if he thinks this is the way to jump-start Doha:

The answer lies in creating a new structure for the Doha development agenda that would yield real gains in trade, offer real help to the least developed countries and provide a significant incentive for further liberalisation. Towards that end, I would suggest… a “plurilateral” agreement among all WTO members willing to move directly to free trade on a global basis. To participate, members would have to eliminate all barriers to trade in goods and services, including agriculture, and immediately decouple all agricultural subsidies from production. What this would do is create a free trade core within the WTO, provide significant trade benefits to its participants that would ease approval of the overall accord back home and provide a significant incentive for non-participating WTO members to join as soon as they were ready to accept these obligations.

No way.

The other prongs of his plan are also desirable but far from likely to happen. For example, you won’t see a deal to harmonize the various preference schemes for LDCs, because those programs are as much about politics as development.
