Yes, the armenian lobby is strong in France, but there are some other facts as well:
1) The political system of France is a presidential system, and what president says, has much more importance compared to lobbies, and everyone else. It's different for Germany.
2) Individual lobbies have much less importance compared to unions in France, which is opposite to USA.
By considering these factors, Armenian lobby cannot do much, as long as we keep their president with us. Also, we cannot always be hesitant only because there are some Armenians in a country. We just need to proceed to achieve what we want, and receive what we want.
Also, France is going to sell us, Spy Satellites, which shows France is already agreed to have cooperations with us.
