Speed of missiles? Suborbital flights are typically set by how far they go. Note you *can* make the missile come down that much faster, but you equally warn the victim that much earlier that you are blowing a corner of his country off the map, so it is rarely done (and would typically require an equal boast about an ability to target areas even farther south than Texas).
I strongly suspect that the rest of the boast is equally absurd. Takeaway: Russia has missiles, just as they have since the mid-1950s. If the missiles launch, the USA and Russia will more or less cease to exist and the resulting economic and ecological damage will likely collapse the nations of anyone not already glowing. And "blowing up Texas"? Are they claiming to be able to launch (and MIRV) the "Tsar Bomba"? I think that even Pravda would have trouble with that one. Better cut off the propagandist's vodka supply.
Reagan's Star Wars ideas are even more futile than George Lucas's (although it might not be such a bad idea to circle North Korea with counter missiles that hit things on the way up. You just need agreements with China to cover the Northern boarder as well).
