I couldn't agree more that the focus of all our actions has to be on the plight of the Palestinians. That's hard, but not impossible, when the mainstream media is focused on what they view as sensational stories like the kidnapping and imprisonment of foreigners. (And, I have to add, primarily foreigners who they think of as "white." The kidnapping and disappearance for days of Press TV journalist Hassan Ghani, a Scottish citizen, got virtually no coverage.)
In my thinking, this journalistic myopia is evidence of the success of Israel's campaign of occupation, apartheid, and erasure. We need to counter it at every possible turn. The success of BDS campaigns around the world tells us that people are ready to understand and act when given an opportunity and the means.
But I also think that challenging the borders and apartheid laws plays a very useful purpose in defining the nature of the occupation. It's just up to us to put it into context by making it clear that the same walls that keep people out keep many more people in. The same "laws" that are used to imprison foreigners have been applied far more harshly to literally hundreds of thousands of Palestinians. Finally, I think, going forward, that people who do decide to challenge the borders should be prepared to challenge every facet of the Israeli "legal" process and fill the jails.
