only problem with that thesis is war drives up oil prices which are imported and used in war. Coal is not imported and is not used in war for transportation fuels. It is used for either producing elec. for the bituminous stuff (thermal coal), or for adding carbon in steel making for anthracite (met coal).
There is nothing of this world that can save WLT now. Except a time machine of course. they need to go back and not buy Western Coal for 2.3 billion bucks....which currently has a value of 0. Oops.
