in the world, well behind Russia and Iran...but more importantly...since we are #1 in CONSUMPTION of NG, our Proven Reserves leave us with 12 years remaining.
When you get into "Estimated" reserves it would be wise to review this link as well...it's a bit dated (2011), but the reality of that time hasn't dramatically changed going forward (i.e. efficiencies, costs etc.)

With proven reserves of 12 years, is it wise to promise supply to the EU for an extended period...what happens when that runs out?...for them?...for us?...and as the Slate article mentions, the NG Industry at that time wanted to power all our Semi-Trucks with NG...that's a big investment in capital that needs assurance of ROI for many years to come.
A 'Prudent' planner would not bet the country's future on "Hope and a Prayer" that we'll have the resources we need for a very long time...not just for heat and power, but irreplaceable uses, like Plastics.
