The following article from the Scotland Herald strikes me as one of two things... Bullshit... or Bullshit. Why would the USA advertise to the world its military plans, it would be tactically impractical, and the only real motive for doing so is to instill FEAR in Iran's leaders. But why stop there... Its likely no war with Iran will ever be fought and they will continue to bank on the proxy wars within the region that rely on Iran's indirect support. Its likely this whole facade is for the purpose of boosting the military industry (while taking attention away from other conflicts i.e. keeping everyone ruminating whether or not they will attack Iran when they are invading everyone else!!!). The thing about this industry is if the products never get used no one is going to be disappointed. If military contractors are needy all the have to do is claim that there is a threat, and that "preventative measures" should be taken, they can then carry out a cold war which is equally (if not more) rewarding for the military industrial complex.
If they do attack Iran, after advertising their plans, I will be surprised,
From the Scotland Herald Hundreds of powerful US “bunker-buster” bombs are being shipped from California to the British island of Diego Garcia in the Indian Ocean in preparation for a possible attack on Iran.
The Sunday Herald can reveal that the US government signed a contract in January to transport 10 ammunition containers to the island. According to a cargo manifest from the US navy, this included 387 “Blu” bombs used for blasting hardened or underground structures.
Experts say that they are being put in place for an assault on Iran’s controversial nuclear facilities. There has long been speculation that the US military is preparing for such an attack, should diplomacy fail to persuade Iran not to make nuclear weapons.
Although Diego Garcia is part of the British Indian Ocean Territory, it is used by the US as a military base under an agreement made in 1971. The agreement led to 2,000 native islanders being forcibly evicted to the Seychelles and Mauritius.
The Sunday Herald reported in 2007 that stealth bomber hangers on the island were being equipped to take bunker-buster bombs.
