Much of your “dictates” are very naive. I will take the example of Intel products found in weapons that are a few 1000 units.

Assume these were 8051, manufactured in billions per year. Or microprocessors from 10 years ago manufactured in 300 million per year for each skew.

Intel uses distributors.

Intel does use distributors to sell their chips. These authorized distributors play a crucial role in reaching customers and providing extensive coverage in regional markets. Here are some key points:
TD SYNNEX: TD SYNNEX is Intel’s #1 volume distributor in North America. Their team members are seasoned experts on all things Intel, offering product fulfillment and full solution design services 1.
Other Authorized Distributors:
Digi-Key: Known for having the world’s largest selection of electronic components, Digi-Key is an authorized distributor of Intel products 2.
Arrow: Arrow is another authorized distributor stocking a wide selection of Intel components and supporting reference designs 3.
Metra: As an Intel Authorized Distributor and Intel Branded Systems Distributor, Metra provides access and support for a full range of genuine Intel products, from client components to high-performance data center systems 4.

Intel ships to many companies is Asia.

How do except Intel to ensure a few 1000 don’t end up in Russia? Of course Intel does police both their vendors and distribution channels. If violations of US restrictions are found the cut off sales.

But really it is like saying no pacific coast ocean water can reach Russia.

You do what you can of course. But your planned exhibits of shame are spitting in the ocean.
