I don't know why we would feel unsafe. Maybe it is because there are dickheads in the world that don't like us? I couldn't tell you why kids twice my age routinely beat me up when I was little, calling me kike, jew boy, etc.
At the time I didn't even know what the hell they were talking about.
I couldn't tell you why they would pin me to the ground hold my eyes open and make me stare at the sun or attacked me while walking home.
I have white skin (well tanned though), I have black hair, brown eyes, speak english, work for a living, etc. I can't tell you why.
Why did a country incinerate, mutilate, experiment on, rape, murder, torture, use for profit and entire race, just because of who they were?
Why do the middle east people like Palestinians, Iranians, Syrians, etc hate the Jewish race? I couldn't tell you. That hatred existed long before the Jewish people settled in what is now Israel.
Don't forgive me for not agreeing with the so called facts that it is the Israeli's fault for the violence. It is no more there fault than it was there fault during world war two and the holocaust that almost exinct an entire race.
