NATO held its largest summit since the Cold War in Warsaw, Poland.
Russian aggression, radical Islamist terrorism, the refugee crisis, Brexit, Afghanistan...
The list of challenges NATO leaders faced at the biennial summit highlighted what some consider to be a post-Cold War moment of truth for the alliance to prove it still matters.
The US-led alliances provocative moves at the Russian border are perceived by Moscow as threatening the countrys security.
Is it justified?
Russias actions in Ukraine, along with a pattern of aggressive fly-bys by Russian warplanes in the Baltic Sea region, have left NATOs eastern flank rattled.
One of the summits key news items was the announcement that NATO will deploy four combat battalions to Poland, Estonia, Latvia, and Lithuania on a rotational basis beginning next year. The battalions will be fielded by Canada, Germany, the United Kingdom, and the United States.
This supplements a previously announced U.S. plan to deploy about 3,500 additional troops to Eastern Europe on a rotational basis.
