Re.. the proposed siting of the missile defence shield in Poland.

The Americans would have us believe that this is to protect the West from attack by a "rogue" state such as Iran.

As most people agree that Iran does not have nuclear weapons at present, or are likely to aquire them in the forseeable future, this excuse seems feeble.
In addition, any attack by Iran on the West would ensure its own immediate destruction by a counterstrike.

I think an all out war for energy will be waged by the West and this missile defence system is the first step in a programme to neutralise any military retaliation by Russia.
America is still the only country to have used nuclear weapons and have shown themselves willing to use them against a rival ideology in the Cuba Crisis.
I am quite sure the nuclear option will be considered very carefully by the people who run America, should their ideology and economic system come under thread from dwindling energy supplies...Ake
