> why did the US shift to a focus of techno-supremacy?

In theory, we (the USA) can develop the tech during peace time and ramp up production during war time.

The problem is that during small brushfire wars, some of our less useful politicians decided to spend huge sums to avoid a few civilian casualties and even fewer US casualties. The more correct path would gave been to consider what weapons we would want to mass produce during a war that threatened our survival and take the opportunity to field test those weapons, not $100,000 artillery shells.
