Germany plans to revamp shelter system in case of Russian attack as fears of a major war rise – Fearing Russia could attack another European country within the next four years, Germany is planning to expand its network of bomb-proof bunkers and shelters, according to reports.
“For a long time, there was a widespread belief in Germany that war was not a scenario for which we needed to prepare,” Ralph Tiesler, the head of the Federal Office of Civil Protection and Disaster Assistance, said in a recent interview as reported by The Guardian.
“That has changed,” Tiesler said. “We are concerned about the risk of a major war of aggression in Europe.”
