But the current stand-off between Netanyahu and Abbas lays bare the duplicity of the situation for all to see.
The PA leader may say the prisoners are the most cherished Palestinian constituency but he also describes his security services' co-ordination with Israel as "sacred".
The security services' role is to assist the Israeli army in foiling Palestinian attacks and in arresting the very Palestinians he extols. Abbas cannot realistically hold true to both positions at the same time.
Netanyahu, on the other hand, has nothing to gain from harming the Palestinian security services, which the Israeli army relies on.
The decision to withhold taxes was taken chiefly to boost his popularity as rival right-wing parties compete for who appears the most hawkish before April's general election.
Paradoxically, in withholding the PA's tax money, Netanyahu is punishing Abbas, his supposed peace partner, while showing a preference for Hamas, Abbas's arch rival in Gaza.
Although Israel categorises Hamas as a terror organisation, Netanyahu has been allowing extra funds into Gaza from Qatar to alleviate the enclave's dire conditions.
Further, there is something richly ironic about Netanyahu rebuking the PA for rewarding Palestinian "terrorists" in the same week he negotiated a deal to assist bringing Otzma Yehudit, or Jewish Power party, into the Israeli parliament.
The party is Israel's version of the Ku Klux Klan, disciples of the late rabbi Meir Kahane, whose virulently anti-Arab Kach party was outlawed 25 years ago as a terror organisation.
So appalling is the prospect of this unholy alliance that even pro-Israel lobbies like the American Israel Public Affairs Committee (AIPAC) and the American Jewish Committee felt compelled to issue statements condemning Jewish Power as "racist and reprehensible".
Netanyahu believes the extra votes Jewish Power will attract to the right in the election will ensure he has the support necessary to build a coalition that can keep him in power.
But there is another glaring flaw in Netanyahu's tax grab.
If Abbas's coffers run low, he will simply send even less money to Gaza, which is already being choked by Israel's lengthy blockade.
That would intensify the unrest in Gaza, which could lead to rocket attacks into Israel and even larger mass protests by Palestinians at the perimeter fence encaging them.
At the same time, if things remain unresolved, an already fragile PA will move closer to collapse and Hamas might then be poised to fill the void left in the West Bank.
Loss of power for Abbas, combined with loss of a security contractor for Netanyahu, appear to make this confrontation mutually self-destructive unless Netanyahu and the right have another card up their sleeve.
