Exactly what Israel call disputed is unclear
Unclear to you - because you're obviously ignorant on the subject.
There's a very clear border - the green line, after which the Israeli law doesn't apply. That area is not part of Israel, and most Israelis, except for some right wing extremists, don't want it ever becoming a part of Israel.
As for the "Berlin Wall" or the other crap you're spouting - I don't feel like educating you about the basic facts of this conflict. Read a little about it, doesn't even matter if it's from a pro- or anti-Israeli perspective. But now you're just bullshitting.
And it's not just because I disagree with you. If you knew the real reason why Israel isn't willing to annex the territories (because it doesn't want to undermine its Jewish majority), you'd have a lot more venom to spew than the incoherent crap you have now.
When Israel are whining over firework from Gaza landing in Sderot, pretending they are V2s, they never mention that Sderot is occupied palestinian territory outside the recogniced borders of Israel
Sderot is not a settlement, and it's well within the Green Line, just like Ashdod and Ashkelon. So you learned two new things today, ok?
