For the US of A, I can think of a few things that resonate with us:
1. prospect of a Democratic Revolution feeds right into our own sense of history - we love seeing The People overthrow a Tyrant, especially when it seems they are doing it on their own rather than via our CIA or military prodding
2. prospect of non-violent means producing social change recalls the Civil Rights era
3. Egypt and Israel are connected, this is geopolitically important
4. Egypt and Arab/Islamic countries are connected, add oil and terrorism to the geopolitical import
5. The Global Caliphate
