Perhaps Israel just doesn’t have those students that want to do these things, like the US has?
There is a vast difference, here. I don't know if you were intending to be factious or not, but I think we need to explore the sociological issues involved.
Israeli children grow up with the threat of random violence every single day. That's very similar top the children in the 50s and 60s who grew up during the Cold War, knowing that war could break out at any moment between the U.S. and the U.S.S.R. Israeli children, as the result of Israel being founded primarily as a religious state, grow up surrounded by religion, God, prayer and an awareness of the religious history of Israel.
Most American kids have no clue what that environment is like. They don't have the fear of an attack at any moment. They haven't necessarily lost friends and classmates to this kind of violence. But, they HAVE been raised in an environment in which God and religion have been under steady attack from the left - INCLUDING the schools!
So, IMO, what we are seeing in America is a vastly different situation than that of Israel and to make a comparison on that basis is unfair.
When we analyze the rash of shootings that have occurred this year alone, we find that they are perpetrated by people who are mentally disturbed or are unable to perform any sort of critical thinking because the schools don't like it when the students can outthink the teachers. And, the demand by the ACLU and other liberal organizations to "mainstream" kids who have mental or emotional issues is not helping those troubled kids. In many cases, mainstreaming only aggravates the situation because the troubled kid may be isolated or teased by his/her "normal" classmates.
To make a long story just a touch longer, the comparison between Israeli kids and American kids is not an apples to apples one, it is an apples to lettuce one.
