re: #161 EPR-radar
To be brutally realistic, the US response if Russia were to start gassing Chechen rebels en masse would be limited to a sternly worded letter and ending some trade deals.
Nothing more we could do if it was Russia. Russia simply remain far too powerful to be attacked “as an object lesson”. And this is true nowadays even without reference to Russia’s nukes, since they now have their own non-nuclear stank-off attack capability.
