America should prevent future attacks by fully acknowledging the threat posed by Yemeni terrorists, ensuring their prosecution when captured, and by continuing current American policy in support of the Yemeni government.

In order to combat piracy, the U.S. and its partners must combat not only the pirates but also the aggravating factors that encourage them, such as illegal fishing and toxic waste. Anti-piracy forces working to protect the seas and prevent the dumping of hazardous waste will earn some measure of good will from Somalis even as they crack down on pirates.

The U.S. can cooperate with India on a variety of fronts: including nuclear non-proliferation, extremist violence in the Afghanistan-Pakistan region, and the maintenance of a stable balance of power in Asia. If President Obama wishes to truly strengthen the U.S.’s partnership with India, he must go beyond mere symbolism and focus on forwarding the U.S. and India’s shared goals.

. To move negotiations forward, the U.S. should proceed with a regimen of multilateral sanctions to put pressure on Iran to negotiate seriously. Sanctions, along with focused and serious negotiations, are America’s best chance to disarm Iran and prevent military action.

While the Kimberley Process has been a good first step, a stronger independent body composed of both exporters and importing firms is needed to regulate both sides of the diamond trade. If enforcement is reliable enough, the profits from the legal trade should be the only incentive needed to ensure participation.

Today, the United States has an opportunity to take action and redefine its Central and South American policy through its response to the ousting of Honduran President Manuel Zelaya. By conditionally acknowledging the new Honduran election and punishing the Honduran military for its actions, the United States can defuse a dangerous situation without evoking the legacy of American imperialism.

Europe, with the exhaustion following the Lisbon treaty and the lack of future direction it provided, will only gain international respect if it can harness the treaty’s potential and work toward a more maximalist EU.

In light of Japan’s history and its important geopolitical position, President Obama should send a clear signal that Japan’s new focus on strengthening ties with its neighbors need not dent the friendship between the U.S. and Japan.

If President Obama wishes to encourage moderate Palestinian leadership and the renewal of negotiations, he must spend his political capital in a manner that reflects the true urgency of the region’s political situation and does not assume, as Mr. Lieberman says, that the region has “learned to live with” violent conflict.

Because Israel was justified in its defensive military operations against Hamas and because it took such strong measures to avoid civilian casualties, the U.S. should continue to support its ally in the face of international backlash against the conflict.
