US LNG exports are coming on to the global gas market at a time of a glut of supply, both pipeline and LNG, and low gas prices.  The outlook for demand - outside the US - is mostly pessimistic as well, suggesting the glut of supply could last for many years. Europe is seen as a key battleground for LNG against Russian pipeline gas but post 2020 China will come into that category as well.  What are the real prospects for US LNG exports with this background; could  Russia engage in a price war in Europe, will there be any more FIDs on large scale LNG export projects before 2020, and what does all them imply for gas prices?
