Anyways, how about we make this "How big can you possibly make Israel and what are the consequences" thread?
Okay! I can roll with that.
Well, to have an Israel that encompasses the Golan, the southern chunk of Lebanon, the West Bank/Gaza, and the Sinai...well...let me take them a bit at a time:
1. An Israeli Sinai: my preferred theory is that the operation to take out the Egyptian SAMs on the second day of the Yom Kippur War is allowed to go through. This would put the SAM net out of commission by noon and have Israeli armoured divisions on the canal by the end of the day at best or day 4 at worst.
Then you just have a government in Egypt which doesn't want to play diplomatic ball with Israel, which is
extremely likely.
2. West Bank/Gaza: This could come out of an Israeli Sinai, as Sadat's diplomatic trip to Israel was what openned the door to the Camp David Accords which in turn helped turn over control of the West Bank and Gaza to the Palestinians.
3. Golan Heights: that's logical. Israel's had control of that off and on forever.
4. southern chunk of Lebanon: The original plan for Operation Galilee, the Israeli invasion of Lebanon in 1982, was for the occupation of a 40 kilometer zone where they would destroy the PLO and make sure they couldn't come back. It wouldn't be hard for the Israeli government to say they were just coming in to stay.
Well...it'd be a harder sell than the first three on this list, but it's not out of the realm of possibility.
