Of all the major European states, France has most acutely experienced the murderous ambition of the jihadists.
Belgium, where the Paris attacks appeared to be planned, was hit in March with strikes on its airport and a train station. The outrages left 32 people dead. But terror returned to France in July when an attacker used a truck with deadly results in Nice, fatally mowing down 86 revellers on Bastille Day.
President Francois Hollande declared a state of emergency after the November attacks, which is still in force. This week, Paris marked the sorrowful anniversary with reflection, and resilience. The reopening of the Bataclan itself was a defiant signal to the jihadists that the murderous movement would not succeed.
The veteran rock star Sting performed at the theatre, opening his show with a tribute. Speaking in French, the British singer said: "Nous ne les oublierons pas"- "we will not forget them."
A purpose of terrorism is to disrupt communities, and succeeds in its evil intention when the place that it targets is incapable of managing to go about its business as usual. The Islamists have struck fear into Paris, but they have not won.
Tourism has softened but not withered in what is a global hub for culture and the arts. The City of Light still holds its power to draw visitors, though the numbers are down, and so is the income that Paris earns from the eight million people expected to spend time in the famous city this year.
Security is much more visible, with more than 6000 soldiers on the streets of the capital, the largest deployment of troops since World War II. In a survey, 59 per cent of French people said the attacks had changed forever the way they view life and a similar percentage still felt "angry".
Tensions are apparent in reports of relations between different ethic and religious communities. Prime Minister Manuel Valls warned at the weekend that "Yes, terrorism will strike us again." But, he contended, "we have all the resources to resist and all the strength to win."
Friends of France - and that includes New Zealand - must ensure it succeeds.
