Yeah, it's not like Al Jazeera is prejudiced in their representation of how things went down. And why are they so upset about the Palestinians and not upset at all about the poor Kurds, who are more numerous and don't have a homeland either? Could it be because the Kurdish lands are occupied by Arabs, Turks, and Persians (Moslem all), so that's okay? The Palestinian land is occupied by Jewish Israel, and that's not okay. Can anyone say hypocrisy?
They talk about these wars like the Arabs we're innocent bystanders. In 67 they were preparing to strike, Israel just preempted them by striking first. In 73 the Armand actually did attack first, from every direction. And Israel still won. Also, every invasion was to capture land for themselves. Other than Jordan, these Arab countries never planned on giving up their gains.
Israel would cease to exist as a country if they allowed the Palestinians to return. That may sound harsh but it is also true. So, they do what is best for their country and keep them out for the good of their citizens. That is a Government's first and most important job, to protect its citizens.
