How can NATO increase contributions by its members to meet the 2% of GDP commitment to defense spending? Should incentives or penalties be employed? And what might they look like? Or is the 2% threshold misleading and the wrong criterion by which to assess member states' contributions anyway?

We want to hear from you. Pose questions, share your thoughts and join leading experts and our NATO Emerging Leaders Working Group for a Twitter debate on this topic on Tuesday, July 29, at 1pm EST in Washington, 6pm BST in London, and 7pm CET in Brussels. We will be using #FutureNATO to join the debate to ongoing discussions ahead of the NATO Summit in Wales in September.
