Apparently, pro-Palestinian activists are planning to arrive in droves at Ben-Gurion Airport on April 15 (to celebrate US tax day?). They say they want to go from there to the West Bank, where they plan on protesting against the occupation. I'm no supporter of the occupation, but neither am I a fan of the idea of hundreds of anti-Israel protesters making a scene at the airport, marching inside Israel and clashing with soldiers in the West Bank.
Israel was quite successful in dealing with last year's "flightilla". Most of the activists couldn't even board their flights, so they didn't reach Israel at all. That should be the strategy again this year.
