Back on the home front... you know it's clear that Iran could be serious about escalating the situation with oil shipping should tankers attempt to run the blockade.
The typical military play is Iran sending mines. The US would counter with mine sweepers, a strategy that worked well in WWII.
Oh what's that? The US slated the middle east minesweepers for decomissioning AND they just made it back to a US port this week to get taken out of service?
