Scroll down to members. I counted 14 organization from at least 11 countries. So yeah , even the 20 was a streach.

This is what I ment. Sorry if it was not clear.

About the other thing, it is subjective. I would not consider something effecting less then 10% of the countries a global thing. But you do have a point there.
