Just a few days after Islamic terrorists in Paris launched a citywide killing spree claiming 132 lives, Jerusalem Mayor Nir Barkat offered the city five pieces of advice, in a blog post for The Times of Israel.

Addressing his message to Paris Mayor Anne Hidalgo and the people of France, Barkat firstly encouraged Parisians to continue their normal routines unhindered. “By restoring routine, we demonstrate the resilience of our residents and send a strong message to terrorism and its perpetrators: we will not succumb,” he wrote.

He said Jerusalem is a city in which the residents in times of need know to take responsibility for one another. He advised French authorities to encourage residents to remain vigilant and prepared in the face of terrorist threats and to be willing to take proactive steps to prevent tragedy.

He called for moral clarity regarding residents — knowing who is a community builder and who is seeking to wreak havoc and cause bloodshed. With the former the city must work to build bridges between communities, and with the latter he said there “is no room for moral obfuscation.” They must be punished according to the law, he wrote.

He said since the outbreak of renewed violence in Israel on the Jewish high holidays, Jerusalem set a goal of having security forces be ready to arrive at any situation within two minutes. He said the municipality works closely with security forces to design strategy to combat urban terrorism, and he has sought innovative approaches that “can provide us with real-time data that helps us keep our citizens safe.”

Lastly, he drew a parallel between terrorist attacks in Jerusalem, Paris, Boston and New York, saying these attackers all share the same ideology rooted in a hatred of the West and Western values.

“Jerusalemites and Parisians share the same spirit of resilience. We mourn and feel the pain of the families who lost their loved one, care for and support our wounded, stand tall and move forward. This must always be our answer to terrorism for it enables us to emerge victorious,” he wrote
