U.S. President Donald Trump said on Tuesday that French President Emmanuel Macron had been 'very insulting' by describing NATO as 'brain dead' as the two leaders prepared to attend a NATO summit. 'It's a tough statement, though, when you make a statement like that, that is a very, very nasty statement to essentially 28, including them, 28 countries,' Trump told reporters as he met the head of NATO in London. 'I think that, you know, you have a very high unemployment rate in France. France is not doing well economically at all. They're starting to tax other people's products so therefore we go and tax them.'
