Intelligence and security analyst and former US Navy intelligence specialist:
Can the naval blockade starve 93 million Iranians?
The plan to bring Iran to its knees through a land blockade cannot succeed.
Stopping food trucks at the border actually means bombing Turkish, Pakistani, Iraqi and Afghani drivers.
On the other hand, even if Iran's access to large and heavy trucks is cut off, food transportation will continue with smaller vehicles.
A ground advance from Iraqi soil to Iran is more like a fantasy than a real plan.
It takes a month to transport armored vehicles to the area, even with non-stop flights; This too in a situation where Iran will supervise all these movements. Fuel depots in Kuwait are also within firing range of Iranian missiles, and Iraqi militias will be waiting on the border.
Washington no longer has military options to force Iran to surrender.
