The recent concern is a situation where Russia or China know that the US is unable to retaliate without pushing the nuclear button and is also unwilling to push the nuclear button.
In the cold war a lot of military planning effort went into ensuring that direct conflict between the US and Soviet Union would escalate to nuclear conditions fast by ensuring that American forces were always in the critical path of a Soviet invasion of Europe. In reality the Americans would have lost a conventional war in Europe quickly, but this reality also ensured tactical nukes would be used to protect against a route and that the Soviets would need to respond with strategic weapons.
There is no trigger for a nuclear war if China invades Taiwan, and there is a lot which could go wrong in SK, Japan, or southeast Asia before nukes entered the picture. Arguably the US nuclear deterrent in Europe is also approaching the point where one could credibly assume that the US wouldn't escalate to nuclear war.
As smart munitions become commonplace its hard to see a world where a country escalates to a wold ending nuclear response over a few thousand well targeted cruise missiles. Even a crippling attack on the continental US military-industrial base with ~100k cruise missiles wouldn't have a fraction of the casualties a single strategic bomb would carry.
