U.S. President Donald Trump has mounted a four-front (trade, immigration, alliances and nuclear policy) offensive against the existing liberal international order designed and maintained by Washington since 1945. Japan has been a major beneficiary of, stakeholder in, and contributor to that global order. Consequently Japan has an exceptional opportunity, while maneuvering to remain close to Washington, to reduce its unhealthy security and economic dependency on the United States, and to educate the U.S. administration on the merits and benefits of the key planks of a rules-based global order and international cooperation.

The changes to U.S. immigration policy and practices are probably immune to Japanese criticism given Japan's own miserly refugee intake (fewer than 100 per year) and opposition to large-scale immigration, despite numerous studies showing the benefits of this in resuscitating Japan's lackluster economy with a shrinking population.

An efficient and trade-dependent economy, Japan had invested heavily in the Trans-Pacific Partnership, whose latent but obvious anti-China premise was always problematic, that has now been dumped. This increases the importance of bilateral and regional free trade agreements, which do not privilege investor rights to profits over consumer and worker rights and environmental safeguards. Japan has benefited hugely from globally integrated supply, production and consumption chains that risk being ruptured by U.S. protectionist policies. Japan must speak up for and defend the rules-based open international economy.
