The stated mineral-supply policy limits a single national supplier to 60 percent while encouraging recycling and domestic production. That still leaves substantial exposure to one source, and purchased material must reach Britain. Commercial diversification also faces a different test when an opponent actively tries to prevent resupply. Buying available stocks away from Britain could deny procurement without attacking a ship. Physical blockade or war could interrupt delivery after a purchase. Industrial planning therefore needs to account for deliberate interference alongside ordinary market disruption.

Supplier diversification and strategic interdiction
Diversifying mineral suppliers does not ensure that supplies can be bought or delivered during conflict.
