The US first strike strategy never relied on the cruise missiles' speed, which is indeed insufficient (*). It relies on stealth planes and bunker busters. While it may have been viable, this would be a very dangerous bet as stealth technologies are not reliable enough. And they are less and less reliable. However it is true that Russian detection capacities are in a sad state but probably not that much.
The missile defense system itself would only be there for the few missiles left undestroyed, especially the ones launched from submarines. And I am pretty sure that its accuracy has greatly improved in the recent years: the 30% accuracy is an old figure but the computing power aboard missiles and the satellite observations have greatly improved.
This still smells like a hell of bet, though, especially as the stealth bombers are less and less stealth.
(*) If we consider that the longest distance between a US airbase and a Russian silo is 4000 km and it must be traveled in less than 10 minutes, then one would need a mach 20 speed! While the X-37B (spatial drone) claims a peak at mach 21, the earlier flight stages are slower and easily detected, and the USA would have to store atlas launchers in Eastern Europe and Japan. More "optimistic" scenarios may be possible if the USA could just target a few political and military heads.
