Gold is a buy whatever its priced at the moment, international tensions are rising from all directions, peak Oil may or maynot exist but we can have tensions and events to pinch supplies from time to time.
Its an even better buy if you are in AUD, as a commodity currency we could easily fall to 65c, a 0.65 AUD and a gold price of 2000 USD would be a top outcome
It is definitely harder to manage these crisis if oil production is falling in the major fields, sure you might find more but the supply side can take a while to catch up
Someone said that peak oil was about price I tend to agree
