Nothing New
To a degree all major militaries like to have as much of their toys, etc. made locally and if they can not keep it local farm it out to a companies in a friendly country. So when the Pentagon says adios to the Russians and Chinese they are in essence saying, somewhat politely, they are potential enemies in real shooting war. So keep your supply chain out of their hands as much as possible. Also, this increases economic leverage against both as the beneficiaries will US and companies in the EU, Canada, etc. as they will not have Russian or Chinese firms allowed to bid.
