The thing about the minesweepers comes from my ex-Navy spouse. He pays attention to exactly what equipment the US Navy has, how much it costs, how old it is, & how difficult it is to replace (they have a lot of ships & equipment that are very difficult to replace because they just stopped making any more of them a very long time ago).
Last year, the Trump admin decommissioned HALF of the US Navy's Avenger-class mine countermeasure ships. So there were 8. Now there are 4.
