Well as a citizen of a US ally (UK), that's all very well but I don't think the world works like that. Europe, Japan and other US allies are collectively huge pools of talent and capital. How much would the US government have to spend to guarantee than nothing thought up or developed in any of those countries ever exceeds anything developed in the US? Is that really a feasible objective?

Nobody in the US decided to let Holland develop more advanced lithographic systems for chip manufacturing, or to let ARM in the UK come up with a more efficient processor architecture.
