Also, what about the West Bank? The PA is decisively not at war with Israel, yet the occupation there is even stricter than in Gaza. The Israeli government seems to view it as a Schrödinger's territory that at the same time is part of the state and not part of the state.
It is wrong to say the PA is not at war with Israel. They currently have a cooperation agreement they are holding to. The PA still compensates any terrorists committing attacks against Israel and disputes Israel's sovereignty. The issue is not resolved as the implementation of the agreements at the Camp David accords were interrupted by the second intifada.
This is what is called an unresolved conflict. It is true that Israel has full military control. The reason the conflict is unresolved is because the Palestinians refuse to capitulate under any circumstances, and because despite all the claims to the contrary, Israel is actually unwilling to destroy, oppressively occupy, or perpetrate a genocide on the Palestinians.
