Jordan was early to join the West and Gulf states in trying to force back Isis as it swept into Syria and Iraq. King Abdullah was seen as standing firmly against Islamic extremism, even where his father King Hussein had reached out to some Islamist elements.
The failed negotiations, and the symbolic tit-for-tat executions, leave Jordan in an unenviable position. While the people are ostensibly united by the horrors of al-Kasaesbeh's death, the havoc across the border with Syria and Jordan's front-and-centre role now as enemy of Isis could have longer term dangers for the regime.
Isis is not weakened by the execution of its female prisoner. Its obsession with global notoriety has been served. Fear reigns, even through the strong talk of the United States and its allies.
While other countries might be emboldened now in committing troops or advisers to the fight against Isis, the unfortunate sight of an Islamic, Arab nation negotiating for its citizen and being treated with contempt by the terror group will give others pause. New Zealand must decide in the next few weeks whether to meet the hint for a 100-strong force from visiting British Foreign Secretary, Philip Hammond.
Prime Minister John Key believes New Zealanders will support a stand against an international menace. Yet the big question is whether limited Western-led 'degrading' of Isis can truly contain a movement born in part of that very form of Western intervention in the past.
Jordan has lived with Islamist agitation for generations yet it flails for an answer to the Isis threat.
