The champagne had barely gone flat before sobering global events made 2016 look like a hangover from 2015.
The new year's news began with Iranian protesters sacking Saudi Arabia's embassy following the execution of a prominent Shiite cleric. A diplomatic split quickly ensued as the Saudis and several Sunni allies downgraded ties to Tehran.
Next was the jolt of jittery equity markets mimicking China's deep dive.
And then the reliably unpredictable Kim Jong Un announced that North Korea had tested an "H-bomb of justice," although most experts judged it to be "just" an atomic bomb.
The globalization of commerce and conflict gives these episodes a worldwide impact, just as other events or trends likely to mark (or mar) 2016. And while few foreign-policy practitioners predict specific dates or exact outcomes, many suggest that the year will be fraught.
The Foreign Policy Association's 2016 "Great Decisions" topics reflect real-time crises (Mideast alliances, ISIL, the Kurds, the Koreas, migration) as well as longer-term challenges (climate change, Cuba and the U.S., the United Nations).
In reaction to these dynamics, President Obama has continued a trend toward multilateralism, said Tom Hanson, a diplomat-in-residence at the University of Minnesota Duluth. Hanson, a former Foreign Service officer who will give his annual U.S. Foreign Policy Update at a Minnesota International Center event on Jan. 26, added: "The problem in working with regional actors is you get caught up in their own disagreements and tensions."
Like those between Saudi Arabia and Iran — countries that are key to reaching a diplomatic solution to the savagery in Syria. That war, along with conflicts in Iraq and Afghanistan, are just three of "10 Conflicts to Watch," according to a Foreign Policy article by Jean-Marie Guéhenno, president of the International Crisis Group. But some that aren't often front-page news — yet — are also on the list, including Libya, Burundi, South Sudan and the Lake Chad Basin. There's cautious optimism about Colombia, Guehenno argues, but caution about the South China Sea, where China has rankled neighboring nations — and the U.S. — with territorial claims.
