    A U.S. Grand Strategy of Restraint

    Jan 21, 2021

    Some U.S. policymakers have expressed interest in a realist grand strategy of restraint. Under this approach, the United States would cooperate more with other powers, reduce its forward military presence, and end or renegotiate some security commitments. What are the policy implications of embarking down this path?

    A Strong Japan-U.K. Alliance Needed to Counter China

    Feb 24, 2021

    With Brexit behind it, Britain faces a question about what role it should play in the world. Assuming it wants to remain a power that can shape—but not dominate—international relations, it makes sense to partner with like-minded states, such as Japan.

    As COVID-19 Makes Clear, U.S. Allies in the Indo-Pacific, Not the Money They Pay to Host U.S. Forces, Are the Value Proposition

    The great value the United States extracts from its alliances with Japan and South Korea is not the money they provide to offset the costs of hosting U.S. forces; the value is the deep and abiding alliances themselves and the liberal, democratic, rule of law market economies and societies to which they link the United States.

    Nuclear Testing Not Needed Now

    Trump administration officials are reported to have recently discussed conducting a nuclear test, breaking a moratorium the United States has observed since 1992. Such a move is not necessary to ensure the reliability of the U.S. arsenal and could increase threats to U.S. and allied security by giving a green light to others to conduct nuclear tests.

    Should the U.S. Move to Strengthen Ties with Taiwan?

    The contrasts in behavior between Taiwan and China during the COVID-19 pandemic show why it could be critical that U.S. policymakers consider advancing U.S.-Taiwan cooperation to enhance Taiwan's security, protect U.S. interests, and preserve peace and stability in the Indo-Pacific.

    For the U.S., South Korea, and Japan, It’s the North Korean Regime, Not Kim Jong Un Per Se, That Is the Threat

    Would Kim Jong Un's death improve U.S., South Korean, and Japanese security? Maybe not. North Korea's advancing nuclear and other military capabilities are driving an expanded set of problems, and while Kim's sudden death might constitute a destabilizing factor for the regime, the available evidence suggests the regime itself is the problem.

    Competition in Iraq

    Tensions between the United States and Iran reached a boiling point in January 2020, when Iranian-backed forces attacked U.S. military and diplomatic facilities on Iraqi soil, and the United States retaliated. Policymakers and experts again asked: Why are we in Iraq? What would happen if we left, and why would it matter?

    Russia's Challenge and Syria's Chance

    With much of Syria lying in ruins, Russia can back a revived United Nations–led peacemaking process, or see the West rebuff its appeals for large-scale aid. If Russia chooses wisely, the West, wealthy Gulf countries, and China could help. If Moscow procrastinates, the West may withhold assistance and continue cooperation with regional partners.

    North Korea Post–Kim Jong Un Reappearance: Expect Business as Usual in the Hermit Kingdom

    Kim Jong Un's return, while it leaves much to be desired in the way of explanation, should send one message to the international audience: North Korea's fate rests still in the hands of Kim Jong Un. And judging by appearances in recent days, Kim does not appear to intend to change the course of his strategy to reduce tensions with the United States.

    Supporting a stable and friendly Iraq is in the long-term interest of the United States. This does not require continuing the combat assistance mission, but would mean maintaining a small force of military advisers to help train and develop Iraqi capabilities so that Iraq could defend itself.
