Unless it was considered worth the effort to try and see if they could just jeopardize the system financially. For example, nation states have the capability to compromize industrial operations with specific viruses. If a uranium enrichment centrifuge can be targeted I don't think any system can be guaranteed to be infection free.

What makes you think they do not need it now?

The lack of any mention of a major military conflict on nytimes.com, cnn.com, and news.google.com is a pretty good indication. You don't need to care about a half-finished GNSS system if you're just bombing ISIS.

Unless you wanna kill it before it is deployed. For example if the U.S. was aware that a nation state was about to pull out on funding for it and wanted to keep the economic dominance of GPS.

Ukraine?

They'd jam GLONASS and block GPS in the area as well, if that were the case.

Ukraine is a major military conflict? Mexican drug related violence kills more per month than what is going in Ukraine for the past 3 years.

Mexican drug wars are violent but do not involve competing state militaries, so I would not call it a major military conflict. It's a criminal problem being solved using the military.

There are no competing state militaries, whilst Russia is involved it's military isn't there in any major capacity.

As far as the fighting goes the Ukraine is negligible considering all the armed conflicts around the world.

In the same vein, alcohol kills more per month than drug gangs. Doesn't make either of those a war, regardless of rhetoric.

Poland welcomes thousands of US troops in NATO show of force

Are you proposing that the US would hack Galileo as part of stationing a few thousand soldiers on an ally's territory?

C'mon man keep up; all hacking now is the Russians. Just like a few years ago it was all the Chinese.

Good point. "now" being of course in the next 5 years.
