PITTSBURGH (AP) — The Kremlin is watching, European nations are rebelling, and some suspect Moscow is secretly bankrolling a campaign to derail the West's strategic plans.

It's not some Cold War movie; it's about the U.S. boom in natural gas drilling, and the political implications are enormous.

Like falling dominoes, the drilling process called hydraulic fracturing, or fracking, is shaking up world energy markets from Washington to Moscow to Beijing. Some predict what was once unthinkable: that the U.S. won't need to import natural gas in the near future, and that Russia could be the big loser.
