Trump and Erdogan address the press as NATO summit begins
US President Donald Trump arrives in Turkey and addresses press with Turkish President Erdogan as NATO summit kicks off
Assessment
A US president is standing beside a Turkish president at the start of a NATO summit. The public posture of these two leaders, whose countries have had tense relations over Syria, S-400s, and Kurdish forces, will signal whether the alliance can paper over internal fractures. Watch for Erdogan's specific demands or Trump's tone on defense burden-sharing.
