Comment by tonytran2015: Despite various unverifiable “Treaties on the Peaceful Use of Space”, space will be the “showground” and battlefield for the most powerful advanced (electromagnetic or particles) weapons. The nation controlling the demonstrated most lethal weapons can turn its space based weapons onto its opponents on earth and demand submission. Resistance by any weak nation is fitile and will make that whole nation vaporized.
This is horrible but will be the basis for the next wave of arm race and the unavoidable future awaiting the whole World. Some nation may decide to mount surprise attack on its existing opponents to avoid losing in the unavoidable coming “show of force” space war.
