> Despite the 2005 Israeli disengagement from Gaza,[21] the United Nations, international human rights organisations, and the majority of governments and legal commentators consider the territory to be still occupied by Israel, supported by additional restrictions placed on Gaza by Egypt. Israel maintains direct external control over Gaza and indirect control over life within Gaza: it controls Gaza's air and maritime space, and six of Gaza's seven land crossings. It reserves the right to enter Gaza at will with its military and maintains a no-go buffer zone within the Gaza territory. Gaza is dependent on Israel for its water, electricity, telecommunications, and other utilities.[21] The system of control imposed by Israel is described as an "indirect occupation".

That being said, the occupation of Palestine nominally under PlO control is sufficient so that Israel is not a democracy.
Not to forget that rockets are routinely fired into Israel from Gaza. So, it seems Israel has good reasons to exercise that kind of control over Gaza.
The standard is occupation of a territory without giving them or its inhabitants the right to vote.
