Space industrialization will produce new and less expensive space transportation systems.Space industrialization will produce radically new materials that will have military implications in terms of increased strength, decreased weight, and various other physical properties.
Where there exist arenas of human activity and inter-relationships and property, there will be disagreements and conﬂict.
We cannot expect these aspects of human nature to change in the next ﬁfty years.
The English adaptation would almost certainly end in "yea", because that's what usually happens to French words, but the c sound would likely remain, IMO.

In William Keith's Galactic Marines series one of the themes of the early novels is how the US Marines fight being absorbed or eliminated.
Space industrialization will also produce very large energy collectors and transmission devices in space.
The second area of concern involves the fact that the Third Industrial Revolution will create property of value in space—communications satellites, information-handling satellites, manned space laboratories, manned and unmanned space factories, solar power satellites, lunar mining stations and outposts, lunar and orbital catapults or "mass drivers," and other facilities.
Among science fiction stories with space flight, the overwhelming majority are about combat, both between spacecraft and between futuristic ground troops.
Not to mention the occasional starship marine assault trying to board a hostile ship while in flight.
There will be "space marines", who generally are found on board combat spacecraft.
