Macron hosts 'Coalition of the willing' summit for European defense and military parade.

Willing to pay: Europe faces the bill for backing Ukraine without the US. Forget last week's Nato summit, where Donald Trump put the alliance through another rollercoaster. It's Bastille Day in Paris, with the “Coalition of the willing” – Nato minus the United States – gathering for a more measured summit on the eve of the traditional military parade down the Champs-Élysées, where aircraft from Germany, Ukraine, the UK, Sweden and Greece will join the flypast.
