At 1945 James Holmes explains why Taiwan does not need nuclear weapons to deter China and would be prudent to focus its attentions in other direction:
So, it seems, a nonnuclear onslaught is what Taipei mainly needs to deter. History has shown that nuclear weapons stand little chance of deterring nonnuclear aggression. A threat to visit a Hiroshima or Nagasaki on, say, Shanghai in retaliation for low-level aggression would be implausible. Breaching the nuclear threshold would do little good strategically while painting the islanders as amoral—and hurting their prospects of winning international support in a cross-strait war.
An implausible threat stands little chance of deterring.
It’s something of a relief to read someone arguing along more prudent lines when we’re seeing so much of the opposite these days. Think of it as a “man bites dog” story.
