Trump, Macron and Erdogan Clash Overshadows NATO Summit

LONDON (Reuters) - U.S. President Donald Trump and French leader Emmanuel Macron clashed about the future of NATO on Tuesday before a summit intended to celebrate the 70th anniversary of the Western military alliance.

In sharp exchanges underlining discord in a transatlantic bloc hailed by backers as the most successful military pact in history, Trump demanded that Europe pay more for its collective defence and make concessions to U.S. interests on trade.

President Macron stood by comments he made last month describing NATO as suffering from a lack of strategic purpose akin to "brain death", and criticised fellow NATO member Turkey, which he accused of working with Islamic State proxies.
