Under Secretary of Defense for Policy, Elbridge A. Colby:
If you're a country like Poland or South Korea or something like that, and you face what you regard as a fairly serious threat, if you embark on let's take a middle powers defense industry initiative and it doesn't pan out or it results in something far inferior, you will pay the cost.
The middle power strategy is based on. It's based on I think, as we said, a faulty understanding of international relations, which is that power is in a certain bracket, will naturally have reason to align and work together.
In that context, we actually are encouraging middle powers not only to work with us, but also to work with each other.
