Star wars not the movie
Seen star wars movie but this is the real space war which is potentially risky.
The US, China and Russia have been building on this for decades including 60 other nations.
With the recent news reports on Hillary Clinton email leaks through wiki leaks revealed that a space war was discussed and also against UFOs by one of her close allies.
The space war could be triggered if any of these countries were ready to hit anyone's satellite orbiting the space it's as simple as that. The satellite orbiting the space for it's country are used to send feedbacks on what is going on in the world and could any time be deployed for military use in the event of the satellites came into conflict.
