Reality check: The history over there is periods of low-level attacks from the terrorists occasionally broken by heavier waves of attacks to which Israel responds by hammering them.
Here is another reality check: every country is under "low-level attacks from the terrorists", for some value of "low". United States had 9/11, France has terrorists shooting cartoonists, and so on. Israel is under more attacks becasue it is aggressively annexing land and due to historical grievances. But qualitatively there is no difference and such attacks even at the level faced by Israel are manageable. As for heavier attacks, that just shows that Israel is capable of defending itself. It was able to defend itself in 1967, and it has been able to defend all its other borders just fine. Hezbollah has far more potent weaponry and Israel had no trouble defending its northern border during the 2006 war.
Pretending that there is something about the Palestinian border is based on a racist notion that Palestinians, among all Arabs and other people in the world, are barbarians who are incapable of anything but violence, regardless of circumstances or how they are treated. Of course, violence perpetrated by Israel breeds violence in its neighbours and it starts to have a momemtum of its own that is difficult to remove, but hyperbole that Israel would be committing "suicide" if it just stops land theft or stops treating Palestinians like subhuman rabble in a Ghetto, is not based on reality.
