End violence on Earth

if we do not want attract it from outer space

Astrophysicists have received a dire warning
about an event that will occur in 2037
An alien civilization has sent humanity a clear signal via the Voyager 2 satellite, launched in the 70s of the last century in the direction of the neighboring star Alpha Centauri. It is currently located at the edge of the Solar System in the Oort belt.
Scientists have deciphered a message encoded in mathematical and astronomical symbols, informing that humanity should be prepared for an event that will occur in early 2037, that we have less than 12 years left to prepare.
This is not the date of the end of the world, but earthlings have been warned that in the remaining years, in order to avoid a catastrophe, it is necessary to significantly increase the amount of knowledge, the quality of technology, the accuracy of observations and analysis - to further improve self-control and collective, planetary consciousness. By the beginning of 2037, humanity should reach a global consensus and agreement to stop conflicts and wars.
End violence to avoid violence that could fall from space.
Or if this cannot be achieved, than unite the military forces of the world's leading countries to repel the first attack from the sky and preserve hope for survival and victory.
