The main reason we Israeli Student aren't as politically active as Americans is that while American Colleges are considered the academic equivilente of the last 2 high-school years in Israel, and generally a good time to get out of home, meet people and have fun, Israeli Universities are actually quite difficult. An order of magnitude more difficult in Exect Sciences where our first year is equivilant to their last year.
In general Israeli BA is equivilent to US Grad-School not to College, which is closer to high-school.

(For example, the american highschool I studied in didn't cover Trigo and Integrals, and hardly any theoretical background)
