Let's hope that Washington has enough wisdom to keep Ukraine, Turkey and South Korea on our side.

This is not the end of the Japan-South Korea dispute, but rather the beginning of a new round.

Can and will Japanese bureaucrats revolt or speak out, when necessary, against the incumbent prime minister of the day the way their U.S. counterparts are in the Ukraine scandal?

Preconceptions and wishful thinking are always the biggest obstacles for understanding reality.

The Trump administration's actions raise questions about the credibility of the Japan-U.S. alliance.

If we can't restore the Japan-U.S. alliance, we must work to refine it together — maybe with a new administration in Washington.

The ramifications of the mistake Trump made are so grave that no leader of an ally or friend of American can ignore it.

When it comes to rational, sophisticated and consistent policymaking, dictators like China's Xi Jinping, Russia's Vladimir Putin and Turkey's Recep Tayyip Erdogan have the advantage.
