Compare and contrast by all means, yes indeed
What is wrong with this picture?
Well, during the recent war with Israel (if you can dignify a highly asymmetric act of attempted genocide by calling it a war) Palestinians certainly took a dim view of those who collaborated with Israel by passing intelligence to the enemy. And no, suspected collaborators were not given much of a trial, and yes, their bodies were not treated with respect. In much the same way, Nazi collaborators in France after World War 2 were executed, generally without much of a trial; and in their cases the mistreatment of their bodies began while they were still alive. meanwhile, the Hamas leadership has condemned the execution of the collaborators and demanded that those who carried it out be brought to justice.
Haneen Zoabi, on the other hand, is an elected member of the Israeli Knesset (as the picture shows). For her participation in the Gaza Flotilla (she was on the MV Mavi Marmara when it was attacked in international waters) - which took place at a time when Israel was not, supposedly, at war with Gaza, and which was wholly peaceful, at least until the IDF murdered nine passengers in cold blood - she received numerous death threats. For doing her job as an MK, the Interior Minister requested that she be stripped of her citizenship and her parliamentary immunity. Other MKs demanded that she be prosecuted for "treason". Eventually she was stripped of some of her parliamentary privileges and banned from taking part in discussions in the Knesset and from voting in parliamentary committees (ie from doing the job she was elected to do). So much for Israeli "democracy".
When faced with those it viewed as actual enemy collaborators (rather than elected members with inconvenient political views) the Zionists who were trying to establish a Jewish state were unrepentant about their murder.
I note that I am not alone in observing that Israel actually treats spies in just the same way that Gaza does, though even when the IDF executed someone who turned out to be innocent the punishment doled out was derisory. In more recent times, of course, Israel declared Mordechai Vanunu to be a spy for telling the world about Israel's uninspected and unregulated nuclear weapons. For this, as Israel does not have the death penalty (a fact its leaders conveniently forgot when Adolf Eichmann fell into their clutches) Vanunu was sentenced to eighteen years in prison. (Though it appears that the Israeli state considered simply having him murdered before deciding to kidnap him and put him on trial.) When his sentence was completed in 2004, he was then subjected to house arrest and other forms of harassment which have meant that he has never effectively been freed and was adopted as a prisoner of conscience in 2007 by Amnesty International. So much for "the rule of law" in Israel. The following prohibitions are still in force:
he shall not be able to have contacts with citizens of other countries but Israel
he shall not use phones
he shall not own cellular phones
he shall not have access to the Internet
he shall not approach or enter embassies and consulates
he shall not come within 500 metres of any international border crossing
he shall not visit any port of entry and airport
he shall not leave the State of Israel
So much for Israeli "freedom".
So to return to the stupid photograph with which we began: of course it is barbaric of Hamas supporters to murder suspected spies and drag their bodies around. that sort of thing was barbaric when it was done to Nazi collaborators, many of whom were guilty of no more than friendship with Nazis. It was barbaric when Zionist terrorists did it to Jewish supporters of British rule in Palestine. However, to imply as the picture does that Israel rewards "collaborators" by making them members of the Knesset, when in fact it prevents them from exercising that role and subjects those it actually considers spies to indefinite detention and punishment with no regard to any "sentence" imposed by a court - that's simply Hasbara (lying in the service of the Jewish state), and bad Hasbara at that.
