That may work to stop oppressors but not so for the oppressed. Indefatigable human spirit and all that.
You may recall the Battle of Britain and their "Finest Hour". Endless nights of intense bombings, living like rats under ground, etc. Perhaps, they were not beaten senseless.
"Live by the sword, die by the sword - and its double-edged. The Israeli's have mostly proven that they are willing to lay it down - for instance, with Egypt."
"Live by the sword, die by the sword." - sure, how can one disagree.
The Israeli peace with Egypt was in self interest. They had already pumped the Sinai oilfields dry and Egypt has a population of well over 100 million. Unlike Palestinian lands needed for defense and reestablishing ancient (i.e. Greater) Israel, they were not as much interested in Egyptian lands. And, they did not lay down any sword, they just promised not to use it against Egypt. Israel is armed to the teeth, nuclear arms included. Israel is living "by the sword".
