Not without foundation - the interview was by Pravda (though unlike NY Times, they have much more open forum for wide range of views) with the [ostensibly paranoid] Russian military expert.
However, he is correct that despite having certain successes (e.g, Sukhoi 4G/5G fighters program) overall, in the pace of their developments, Russia has lagged far behind not only the U.S. but is also being overtaken by the Chinese, who successfully clone / "shan-zhai" some of the better ideas of Russian and U.S. weapons programs.
Hell they may already have something.
They have had big problems with their delivery systems. Bulava-30 / SS-NX-32 has had only a couple of successful trials in the span of last five years and will be unreliable if / when actually deployed (with correspondingly great fanfare, I am sure) in relatively small numbers. In either case, they have no illusions about winning a direct confrontation with the [even weakened by her own government] U.S., and this is not something one supplies to the proxies (like Iran, Venezuela, formerly Cuba etc.)
All in all, it gives both sides another excuse / incentive to recycle and sell / purchase the material in the old warheads while doing nothing to preclude the U.S. developing and deploying the new missile defense systems - that's where Republicans played important role.
Ramifications here are mostly political, not defense-related - unnecessary "win" for Obama, singles out and raises importance of Russia as if they still matter as a direct and the only (by nature of bilateral agreement) military opponent while ignoring the "new world order" where rogue regimes are "independent" players.
