Written by Michael Mazza. The new Biden administration will have its hands full from day one. Even as it focuses its energy on finally getting a handle on the COVID-19 pandemic, the administration will have to recalibrate its China policy, making numerous decisions about which aspects of the Trump administration’s approach to keep and which to jettison. Beyond China, it will have to meaningfully strengthen alliances and security partnerships worldwide, make a decision about how best to rein in Iran’s nuclear program going forward, and work quickly to preserve (or not) the New START arms control agreement with Russia. Taiwan policy, on the other hand, should not require significant deliberation in the early going.
