Vladimir Putin ordered his military command to put the Russian deterrent forces on alert. These are Russian military units, which include nuclear weapons. In simple words, it put the huge Russian nuclear arsenal on alert.
The Russian president justified his order by saying that he did it after the aggressive statements of the leaders of the NATO member countries. In fact, shortly afterwards, Russian Defense Minister Sergei Shoigu said that after Putin’s order, Russian strategic missile troops, nuclear submarines in the Pacific and the North, as well as strategic air force were already on alert.
The ten basic things
The US Federal Emergency Management Agency (FEMA) has occasionally published expert guides for such nightmares, and now anyone on the internet can read some basic things to do when the buttons are pressed. This guide is 241 pages (https://www.fema.gov/sites/default/files/documents/fema_planning-guidance-response-nuclear-detonation.pdf) and states, among other things:
The first and foremost thing we need to do is get into the ground. That is, to hide in a basement or shelter. The issue, however, is how we will survive in there. So one should have with him:
1. Water at least for the first 72 hours from the moment the nuclear bomb falls. (Here we have to calculate that man needs 3.5 liters per day)
2. Food for at least 3 days and definitely packaged.
3. Radio with batteries. When the bombs fall there will be nothing on the surface. And of course there will be no TV, internet, electricity, cell phones. Communication will only take place via radio.
4. First aid box
5. Flashlight with batteries. (As we said there will be no electricity at all)
6. Whistle. As in earthquakes, the whistle helps to locate someone who is buried under the rubble.
7. Mask. Not the masks we wear for the coronavirus, but a mask with an activated carbon filter.
8. Wet wipes, for hygiene reasons
9. Maps of the area where we are
10. Tool toolbox with basic tools that we will find useful later.
