That's not how the US operates, the US does owns the core component and software packages.And some people would say how come every year added the GDP the size of Netherland but can't make EUV machine which Netherland can ... well only country can currently. The US can't make even any DUV machine, let alone DUVi or EUV
So if those vassal economies don't do what the US wants them to do they can break complete modern high tech western economies by imposing export restriction. Like if the US say no more CYMER EUV light source ASML is fucked. Same with the US restricting export on key chemicals needed to produce semi conductors.
