On the web: Moscow’s terror response, G20 rumbles, US foreign policy, and libertarians at sea…

– With Moscow still smouldering in the wake of the metro bombings, Sam Greene assesses how the Kremlin might respond, suggesting that recourse to further authoritarianism is unlikely to prove productive. The Economist, meanwhile, highlights the need for greater awareness across Russia of the fragile situation in the north Caucasus and notes the lack of a measured political discourse in response to the attacks.

– Francis Fukuyama talks to former US Treasury Secretary, Henry Paulson, about China’s approach to the financial crisis. Daniel Drezner, meanwhile, reports on the discontent of leading G20 countries at Beijing’s apparent insouciance over implementing agreed economic reforms.  Elsewhere, Patrick Messerlin charts the actions of the emerging G20 powers across economics, trade, and climate – suggesting that while much progress has been made, they still require leadership from OECD countries. Oxfam’s From Poverty to Power blog, meanwhile, offers a progress update on the financial transaction tax.

– Elsewhere, Der Spiegel interviews the man that headed Obama’s transition team, John Podesta, who offers his thoughts on the healthcare debate, the Washington political process, and Obama’s engagement with the rest of the world. The FT’s Edward Luce and Daniel Dombey, meanwhile, assess the centralised nature of foreign policy decision-making in the Obama White House – highlighting the emphasis placed on improving the inter-agency process compared with the Bush years, but also the lack of a grand strategic thinker to which the President can regularly turn (à la Kissinger).

– Finally, Prospect Magazine has an interesting article on “seasteading” – described as involving “a future in which the high seas will be increasingly commandeered for unconventional purposes” (such as medical tourism, gambling, sanctuaries for minority groups etc.) – and the opportunity it may present for the creation of “micronations” populated by libertarian-minded groups.
