Group behind "Nakba Day" attempts to invade Israel calls for more riots, launches new plot for mass landing at Israeli airports

The first incident was for "Nakba Day," and the next is to commemorate the start of the Six-Day-War. You may be noticing a pattern: these spectacles are designed to demand a do-over for wars in which Arab Muslim states were handed embarrassing losses when they thought they could polish off the Jewish state fairly easily, once and for all. They want to take another shot at it, or at least create enough trouble to goad a credulous international community into making land grabs on their behalf in consolation for military conflicts they could not win.
An update on this story. "Palestinian group calls for more 'Nakba Day' style riots," from the Jerusalem Post, May 21:

The Pro-Palestinian group that organized "Nakba Day" marches announced on Saturday that they were planning further protests on June 5, the day that the Six Day War broke out. The announcement, which was published on the Internet, called on Palestinians in foreign countries to fly to Israel and land at airports within the state.
