TOKYO — President Barack Obama traveled to Japan this week for the G-7 summit and a landmark visit to Hiroshima, but the trip also came at a fragile time in the 70-year-old alliance between the two countries. The partnership finds itself under greater scrutiny amid the Asia-Pacific region’s shifting geopolitics.
In his first term, Obama outlined what he said would be the United States’ strategic pivot to Asia, home to four the top 10 U.S. trade partners and nearly two-thirds of global economic growth. It was to be a rebalancing of U.S. interests in the new century. And now, as China lays claim to disputed territory in the South China Sea and North Korea continues its nuclear weapon threats, the world will see if the U.S. rebalance is up to the challenge.
