The pressure on Iran has driven it to make explicit and public its plan to close down the Hormuz Strait in case of war. According to Tehran Times, Iran plans to hold a war game in the near future to practice its ability to close the strait. The option was always there but no one talked about it because each mention only brought nearer its occurance. Closing the Strait is a casus belli of the highest rank. American soldiers loitering in Fort Hood will shortly start to train for opening up the Straits.
