Basically, the shield removes the MAD principle, by making it so that we can nuke Russia but they can't nuke us. Since most missiles can be shot down manually in the time it takes them to get from Russia to North America, Russia's primary target in nuclear war would be Europe. Kind of like how when you can't kill Batman, you go after everyone he loves and cares about. The shield takes that away too.
Which makes this politically awkward for Russia, because they are basically saying "We demand the right to vaporize smaller and weaker nations without interference!". While it's somewhat justified, it's a hard line to sell.
