We are talking about all settlements into territory that was not Israel's regardless of the year. The settlements like that are internationally illegal precisely because they are clear attempt to use civilian population as shields in a land takeover.

What territory wasn’t Israel’s? And when? And at what point?

West Bank, Gaza, East Jerusalem, Golan Heights.

Formerly: South Lebanon, the entire Sinai peninsula.

New and improved: Mt. Hermon, UN buffer zone in the Eastern Golan Heights.

Any territory which Israel occupies without granting the local population citizenship is definitely not Israel's, by their own admission.
