Difference from TWG: to be examined
George Monbiot's book The Age of Consent describes the action almost similar to our way: to form the provisional World Parliament without waiting help from existing nation-states and without hope that they would disappear. On the first phase it will have rather moral authority. Its influence will grow by degrees, it shall try to control existing world institutions and it should decide itself whether some kind of world executive body is necessary to create.
This program was suggested to Global Justice Movement and World Social Forum participants. Now Mr.Monbiot is British Guardian columnist.
Difference from TWG: George Monbiot says general election is likely to cost $5 billion, while we (taking into account Internet and mobile phones development through 10 years) think that it can be organized without centralized budgeting at all.
We have contacted George Monbiot to invite him to join our activity as the difference between our approaches is quite a little.
