But in the global context, between adversarial nations, or even countries that don't see each other as equal, it is absolutely foolish not to copy. Since everything is framed in terms of game theories, what is even the benefit of not copying and being a "good boy" country?
In fact in this situation a country's IP is almost its liability and not its asset. Because it should cost the holding country money and resources so their citizens' IP is protected. And these resources are better off preserved for more crucial knowledge.
None of this even makes the copier's actions bad or immoral. They have a moral imperative to succeed.
