Trump reneging on a deal ... Refusing to pay... When has that ever... Oh wait...
Unfortunately like the grown and harvested crops for USAD already in warehouses, that DOGE cancelled contracts on. Small farmers awaiting their payments to then pay off the seed and costs to plant again left in lurch.
Trump can do the unprecedented and just cancel all the funded contracts underway for Bidens approved programs. US Military logistics probably doing heavy lifting, and Trump could throw a spanner in there too.
A number of programs probably/necessarily under longer term multi-year contracts to keep continuous manufacturing work going. Otherwise manufacturers won't expand production staff or facilities.
The continuous supply of long lead-time items, even new work like electronic countermeasures, or redesign of stinger with modern components.
