World leaders are meeting in Newport, Wales today for the start of a two-day NATO summit.
In his welcome, British Prime Minister David Cameron called NATO "the anchor of our security," and said "over the next two days, we must reinvigorate and refocus this alliance to tackle new threats and to ensure it continues to foster stability around the world."
Two of those new threats that are dominating the conversation in Wales are the conflict in Ukraine and the recent, dramatic rise of the Islamic State, or ISIS, in Iraq and Syria.
Here & Now's Jeremy Hobson gets the latest on what's happening on day one of the NATO summit from NPR international correspondent Ari Shapiro.
