Yes, they will be rewarded . . . but not if it is in a global conflict, or not many at least. Just as in the early stages of WW II there were Americans who fought on, or sold to, both sides until the US got into the war.
But I don’t see how there can be much disagreement over where the shale is in a place like Russia. It is incredibly distant, in frozen over tundra, with virtually no support structures at all.
It is somewhat more accessible in China, except that it’s in provinces that aren’t exactly the most secure for the ChiCom government.
There’s a lot more world than China and Russia. That’s what I mean.
