Security Cooperation


The NATO alliance served its participants well in countering the strategic threat once posed by the Soviet Union, but the rise of other regional powers and coalitions since end of the Cold War has prompted a reevaluation of existing alliances. RAND research has provided policymakers with essential information on how best to forge new defense cooperation agreements and strengthen old alliances to counter emerging security threats.

    India Is Becoming a Power in Southeast Asia

    The moment has been long in coming, but India is turning into a strategic actor in Southeast Asia. Even though the United States and its Asian treaty allies are not involved, India's moves raise the tantalizing possibility that it will increasingly complement the U.S. Indo-Pacific strategy to counter China in the coming years.

    An escalating war of words between Beijing and Seoul is raising pressure on South Korean President Yoon Suk-yeol to take a softer line with China. Instead, the Yoon administration should see Beijing's threats of punishment as vindication for further strengthening and expanding Seoul's alliance with the United States.

    It is time to create a multilateral Arctic fisheries management plan before a moratorium on fishing in Arctic high seas sunsets in 2037. Agreements can lead to economic and food security for partners; a lack of coordination will lead to conflict, environmental degradation, and overfishing. The clock is ticking.

This matters because, as the Ukrainian war demonstrates, a protracted struggle could require different plans from the ones Japan is possibly making.

The debate over congressional support for Ukraine aid largely revolves around means. But what of the other two legs of the strategic triad?

    Both terrorism and coups are on the rise in the Sahel. To reverse this troubling trend, the United States could ramp up support aimed at improving security governance, professionalizing militaries, and strongly sanctioning all forms of military takeovers in the region. This would require a real shift from the current U.S. security approach in the region.

    After months of publicly lobbying to acquire U.S.-made F-16 fighter jets, it appears that Ukraine may receive them later this year. However, there remains a long road ahead before the F-16s would see service in Ukraine—and it is an open question how much they would affect the outcome of the war.

    Military Assistance to Ukraine Is a Rare Success

    Recently, the United States reversed its long-standing opposition to sending Ukraine F-16 advanced aircraft to aid its fight against Russia. The policy reversal is a smart call. Once the aircraft are delivered and training is complete the jets will help Ukraine defend its territory more efficiently, and might even help end the war.
