John Foster has spent his working life as an oil economist. He understands the underlying role played by oil and gas in international affairs. He identifies the hidden issues behind many of the conflicts in the world today. He explores military interventions (Afghanistan, Iraq, Libya, Syria), tensions around international waterways (Persian Gulf, South China Sea), and use of sanctions or political interference related to petroleum trade (Iran, Russia, Venezuela). He illuminates the petroleum-related reasons for government actions usually camouflaged and rarely discussed publicly by Western politicians or media.
