I do not think the US is prepared for how this is going to go.
I think we might just get stomped down by a country many folks here think of as "backwards" & believe to have far inferior military capabilities.
If Iran is laying mines using small boats, & the US has just 4 minesweeper ships, who is better equipped? Seems to me, the US can keep shooting those boats & Iran can just get more. But if Iran destroys their minesweepers, well, they're gone.
