نتانياهو يؤكد ان العملية البرية في غزة تهدف الى "ضرب الانفاق الارهابية"

With Israelis, you just never know. The 1982 Big Pines Operation in Lebanon, allegedly triggered by an attack on an Israeli diplomat in London by PLO elements, was actually staged by Mossad to give pretext to an operation that Israel was then prepared to execute in Lebanon.
In Gaza, you just do not know whether the HAMAS is that stupid to provoke the Israelis and this Prime Minister, or if the Israelis were ready to degrade the HAMAS missile inventory now that Sisi is in place in Cairo and the border crossing, opened during Morsi's time is now closed, and so caused the provocation.

And there is this other matter of the off shore oil. Is it off of Israel's shore or Palestinian with the Gaza? Already, Israel is trying to draw the international boundary lines at sea so as to capture some of the reserves that were discovered in Lebanese national waters.
Gaza with oil revenue would be a real security issue for Israel, as would Lebanon with oil revenue and with Hezbollah in control of the country. So, again, one must wonder about the timing of this operation, whether the HAMAS provoked it or whether the provocation was manufactured because of the timing and the need for Israel to act now.
