I'll give you an example of how it manifests itself.
When the United States announced its strategic pivot, part of that announcement also said there would be base closures in Europe, there would be reductions of brigades, and there would be reductions of troop commitments to Europe. That's influenced by fiscal constraints on the United States, by whether it can afford to maintain previous levels, but also by those levels being affected by changes in strategy, indicating that it is not the primary interest anymore.
So, yes, absolutely, nations will sharpen and decide what they do based on fiscal constraints, and those are some of the things that you are seeing, such as the Dutch eliminating all of their tanks as part of their smart defence initiative, because they can no longer sustain that capability. But there are ways to address it.
