Most of the suicide bombers live in Area A, until now under PA civil and security control. Israel is not in control there and the PA has not only not discouraged the phenomenon, but has blessed it. Israel has repeatedly given the PA information about various terrorists planning suicide attacks and the PA has done nothing about it. In fact, the terrorist who committed the PAssover eve bombing was freed by the PA days before to go commit the bombing. This is precisely the reason why Israel has now gone and entered into Area A, to catch the terrorists, their weapons etc.
