Teribus,
The civil war by definition must be restricted to England.
The reason Cromwell needed to take decisive action in places other than England (and this, by good luck rather than good management, returns us more or less to the intention of the thread) is that he felt obliged to uphold and perpetuate the folly of his self-deposed predecessors.
England should never have been in the position where she needed to put down a rebellion in Ireland.
