The 32 members of the NATO alliance are in the Netherlands for a summit that has been overshadowed by efforts to de-escalate tensions in the Middle East.        World leaders are being encouraged to set a goal to spend 5% of their GDP on defence by 2035. US President Donald Trump has pushed for that target, but does he have a plan on what's next for NATO?     On today's episode, Niall Paterson is joined by Security and Defence Editor Deborah Haynes who is at The Hague with a front row seat to the meeting.   This episode contains bad language.
