In some parts of the country, standing up for Israel is controversial, even dangerous.
On the campuses of places like Harvard, Columbia and the University of Pennsylvania, anyone who dares to wave an Israeli flag — or, increasingly, wear a kippah in public — is at risk of being assaulted by angry mobs of people with their faces covered.
In Los Angeles, a pro-Israel protester was allegedly killed by a pro-Palestinian computer-science professor.
