US blockade of Iranian ports is a 'gamble': Can it work
There is no doubt that the US military can block ships entering and leaving the Persian Gulf.

TL;DR
- The US military is capable of blocking ships entering and exiting the Persian Gulf.
- A blockade is considered less risky than direct military confrontation and could cut off Iran's main source of income.
- Past blockades of Venezuela and Cuba demonstrate the feasibility of such operations.
- The US Central Command states the blockade will be impartial but will allow humanitarian aid under inspection.
- Iran might withstand the blockade, potentially leading to higher oil prices and pressure on the US.
- China, a major importer of Iranian oil, could be influenced by this move.
- The overall effectiveness of the blockade remains uncertain, described as a gamble by Trump.
