Kharg island. The key.

Kharg Island is a coral island approximately 8 kilometers long, strategically located at some 30 kilometers from the Iranian coast.
Satellite images show huge loading jetties extending into the sea.

This is where pipelines from the vast oil fields in central and western Iran converge.
Interestingly, the whole installation was built in the 1950s by the American oil company Amoco, before its confiscation during the 1979 islamic revolution.
Bombing Kharg Island would strike the Iranian regime at its core, but the economic consequences will be equally devastating. Experts warn that destroying Iran's daily oil exports would send the global energy market into freefall.
According to energy expert Neil Quilliam of the think tank Chatham House, the oil price, which had already peaked at $120 per barrel due to the ongoing unrest, could easily shoot past $150 per barrel.
Lynette Nusbacher (fmr intel officer) warns of a global prolonged, strong disruption and an equally explosive price increase on many, many goods.
