There are military capabilities of GPS that aren't available to non-military users, especially when selective availablity (SA) is enabled. There are apparently no such plans to limit Galileo's accuracy, even in wartime. When we side enables SA, the accuracy drops to somewhere around 100 meters, seriously limiting its military utility. Galileo, on the other hand, seems to be yet another example of the old communism adage about the West selling the rope to those who would hang them.

In the end, if it comes down to letting our troops get killed by weapons that benefit from Galileo's accuracy, I have no problem with employing means, reversible or not, against the system. That doesn't necessarily mean destroying the satellites (very tough to do under any circumstances, but especially out in deep space), but there are other ways...
