They've known about those deposits since the 70's.
In the 90's the only nation to have vast deposits of lithium and other electronics-making minerals/resources was China..and China (and the US) knew those resources wouldnt last very long. Not so long ago ( i believe 4 months?) the news reported China was preparing to cut back on production of stuff that used those resources which were becoming scarce.
Other Nations that have deposits are already industrialized or are in an advanced stage of industrialization (USA, Europe, Russia, India and some African nations) so the price of the material would be substantially higher than the cheap-labor Chinese mined stuff.
New source is needed.
OH LOOK theres a tons in Afghanistan where there's zero industry, where there's US troops already there and its a nation thats currently in a political vacuum.
how.. convenient.
