The Bear and the Dragon

In The Bear and the Dragon, the future is very near at hand indeed. Newly elected in his own right, Jack Ryan has found that being President has gotten no easier: domestic pitfalls await him at every turn; there's a revolution in Liberia; the Asian economy is going down the tubes; and now, in Moscow, someone may have tried to take out the chairman of the SVR--the former KGB--with a rocket-propelled grenade. Things are unstable enough in Russia without high-level assassination, but even more disturbing may be the identities of the potential assassins. Were they political enemies, the Russian Mafia, or disaffected former KGB? Or, Ryan wonders, is something far more dangerous at work here?
