Keep in mind Israel is a sovereign nation with a military that is one of the most expertly trained and fiercely motivated in the world. Blowing up cars, stoning people, or making threats in the general vicinity of an Israeli solider IS suicide. Everyone in that area knows that any manipulation or intimidation of the Israeli government with violence or threats of violence will be met swiftly with action, and it will be decisive.
Picture Israel as a honey badger surrounded by a pack of hyenas. One of the hyenas(Palestinian activists) keeps creeping in on the honey badger, showing it's teeth, growling... occasionally taking a little nip, but never really engaging in a full on attack. After several minutes of a standoff like this, the rest of the pack of hyenas(Iran, et al) continues just standing by watching without really reacting, besides occasionally rallying the lone hyena to take another nip at the badger. Finally the badger snaps, and tears the ****ING FACE off of the hyena. The other hyenas jump back, and then run off to the UN complaining that the badger was being a bully.
You **** with a badger, you get what you deserve.
