Germany is developing an app to help people locate the nearest bunker in the event of attack. Sweden is distributing a 32-page pamphlet titled If Crisis or War Comes. Half a million Finns have already downloaded an emergency preparedness guide.
If the prospect of a broader conflict in Europe seems remote for many, some countries at least are taking it seriously – and, in the term used by Germany’s defence minister, Boris Pistorius, taking steps to get populations kriegsfähig: war-capable.
Russia’s full-scale invasion of Ukraine has dramatically raised security tensions across the Baltic region, prompting Finland and Sweden to abandon decades of nonalignment and join Nato. Military capability, however, is not all: citizens have to be braced too.
Because you can send an alert on the phone, get the coordinates and the person to the next shelter. There are early warning systems, so that is somewhat possible. Ukraine and Israel use such apps very successfully.
EDIT: Obviously it should not be the only option.
