NATO Leaders Present United Front Amid Bitter Differences Patsy Widakuswara LONDON - NATO leaders are gathering at a golf resort outside of London Wednesday to present a united front amid bitter differences over terrorism, Turkey and increased burden sharing with the United States. The 29 leaders, including U.S. President Donald Trump, posed for a traditional "family" photograph before retreating for the planned three-hour meeting. The leaders are expected to release a statement afterwards promising to focus more attention on the challenges posed by Russia and rising superpower China. On the sidelines of the meeting Wednesday, Trump met with Turkish President Recep Tayyip Erdogan. The White House said "the two Presidents discussed the importance of Turkey fulfilling its alliance commitments, further strengthening commerce through boosting bilateral trade by $100 billion, regional security challenges, and energy security." A day earlier, leaders had gathered for informal meetings to mark the 70th anniversary of the alliance's founding, but the day was overshadowed when tensions between President Trump and French President Emmanuel Macron broke out in full public display. Macron vs Trump In an almost 40-minute session with journalists the two leaders clashed on a number of issues including burden sharing within NATO, terrorism, Turkey's invasion in northern Syria, and the U.S. withdrawal from an arms treaty with Russia. The two leaders met hours after Trump criticized Macron for his recent statement describing NATO as experiencing a "brain death," due to diminished U.S. leadership. Trump called it a "nasty statement." .
