Right on. Every airplane flying passengers will still have our GPS 
system on board. The european gps if it ever is built will broadcast 
on three (3) channels so even if one was degraded a little bit it 
wouldn't matter much. They will need to keep our system if they ever 
want to be able to fly passengers into US or NATO controlled 
airspace. It will be at least 10-15 years before such a system could 
be in place and certified by the airlines. By then Eagle would be at 
the end of its life anyway.

If we just give up whole freq bands because we are scared of the big 
bad europeans who are drowning in socialist social program debt, then 
we deserve to lose our bands if we give up without a fight. If a 
country tries to take away our bad because of this "bad science" then 
we should fight them in court and in the public relations area. I say 
figure out a way to use and justify our L band in WWIII that we find 
ourselves in now. Are we not now recognized at least in this country 
as the last line of communications in case of attack? Plan for a way 
to use Eagle when the next attack or hurricane comes our way.

If L band makes sense from a technical point of view then build and 
deploy it. let the political battles come and be fought if they must 
after that.
