The Israeli goal in Gaza is to destroy HAMAS and to replace it with the Palestinian authority from West Bank

This makes the most sense as Israel is not in a position due to global relations to completely exterminate the people of Gaza.

On the other hand they are unwilling to put up with HAMAS any longer.

The Palestinian authority has already been subjugated and bent to the will of Israel and would make for a perfect pro-Israel fit to rule over the Gaza strip.

Conclusion:

HAMAS will be killed off. Israel will install the Palestinian Authority in Gaza as the de facto leaders. Israel will punish Gaza by taking a chunk more of their land permanently.

Expect biblical styled punishment for the people of Gaza before this is all over.

At least one disease outbreak killing multitudes of the people in there.

Israeli's are old school. Every time they have a fight with the Arabs, they punish them by taking over more of their land.

We can expect Israel to take over 10% of the Gaza strip at the end of the current endeavor.

Israel's win in Gaza is guaranteed, and with the death of HAMAS, the Islamic faith is further deradicalized with the death of its most extreme adherents.

The 21st century is going to see a continuation of the deradicalization of extremist Islam.

While Islamic nations may not liberalize along the lines of current day western states, we will see a continuation in the loss of power of the Imams and other religious figures in Islamic nation states.

With their position taken over by the Monarchs and constitutions of these territories.

Israel is destroying one of the four deadliest terrorist groups in the world.

After the destruction of HAMAS, the next primary target would be ISIS in Syria, the destruction of which would further stabilize the Middle East and bring peace to Islam.

A primary western objective in the years ahead will need to be the stabilization of Syria, whether it be by invasion, or letting Assad take over the entire state himself.

We can expect Syria in the long run to break into two parts. With one part being the emergence of a Kurdish state.

In conclusion:

Radical extremist Islam is dying out as it failed to win anything of relevance. ( excluding Taliban )
