Про Китай (боян, конечно, но актуальный):
China's nuclear arsenal is even more vulnerable to a U.S. attack. A U.S. first strike could succeed whether it was launched as a surprise or in the midst of a crisis during a Chinese alert. China has a limited strategic nuclear arsenal. The People's Liberation Army currently possesses no modern SSBNs or long-range bombers. Its naval arm used to have two ballistic missile submarines, but one sank, and the other, which had such poor capabilities that it never left Chinese waters, is no longer operational. China's medium-range bomber force is similarly unimpressive: the bombers are obsolete and vulnerable to attack. According to unclassified U.S. government assessments, China's entire intercontinental nuclear arsenal consists of 18 stationary single-warhead ICBMs. These are not ready to launch on warning: their warheads are kept in storage and the missiles themselves are unfueled. (China's ICBMs use liquid fuel, which corrodes the missiles after 24 hours. Fueling them is estimated to take two hours.) The lack of an advanced early warning system adds to the vulnerability of the ICBMs. It appears that China would have no warning at all of a U.S. submarine-launched missile attack or a strike using hundreds of stealthy nuclear-armed cruise missiles.

Many sources claim that China is attempting to reduce the vulnerability of its ICBMs by building decoy silos. But decoys cannot provide a firm basis for deterrence. It would take close to a thousand fake silos to make a U.S. first strike on China as difficult as an attack on Russia, and no available information on China's nuclear forces suggests the existence of massive fields of decoys. And even if China built them, its commanders would always wonder whether U.S. sensors could distinguish real silos from fake ones.

Despite much talk about China's military modernization, the odds that Beijing will acquire a survivable nuclear deterrent in the next decade are slim. China's modernization efforts have focused on conventional forces, and the country's progress on nuclear modernization has accordingly been slow. Since the mid-1980s, China has been trying to develop a new missile for its future ballistic missile submarine as well as mobile ICBMs (the DF-31 and longer-range DF-31A) to replace its current ICBM force. The U.S. Defense Department predicts that China may deploy DF-31s in a few years, although the forecast should be treated skeptically: U.S. intelligence has been announcing the missile's imminent deployment for decades.

Even when they are eventually fielded, the DF-31s are unlikely to significantly reduce China's vulnerability. The missiles' limited range, estimated to be only 8,000 kilometers (4,970 miles), greatly restricts the area in which they can be hidden, reducing the difficulty of searching for them. The DF-31s could hit the contiguous United States only if they were deployed in China's far northeastern corner, principally in Heilongjiang Province, near the Russian-North Korean border. But Heilongjiang is mountainous, and so the missiles might be deployable only along a few hundred kilometers of good road or in a small plain in the center of the province. Such restrictions increase the missiles' vulnerability and raise questions about whether they are even intended to target the U.S. homeland or whether they will be aimed at targets in Russia and Asia.
