"We find that the easement of checkpoints makes subject populations less likely to support violence against Israel, or the militant Islamist group, Hamas. This suggests a rethinking of Israeli security policy, as short-term concerns over Palestinian movement may be compromising Israel’s long-term interests." Can you imagine American political scientists offering recommendation for the best "long-term interests" of Hamas or Hizbullah? So the authors would like the Israeli occupation to "ease" the checkpoint to facilitate ruling the subject populations. See why I have been totally alienated from the field of political science since my graduation (if not earlier)?
