There's GOTTA be at least one planner on the PSE side saying, "Once Israel comes back into Gaza, tanks in the streets will be all you'll see in the media, and we get to message about our oppression." For example:
http://news.yahoo.com/s/afp/20060628/wl_mideast_afp/mideastunrestpalestinianabbas
''Palestinian president Mahmud Abbas has slammed an Israeli ground offensive in the Gaza Strip "collective punishment" after civilian infrastructure was damaged in air strikes. ''
http://www.ynetnews.com/articles/0,7340,L-3268484,00.html
''Palestinian President Mahmoud Abbas condemned Israel's operation in the Gaza Strip, saying the IDF's first incursion into Gaza since last year's pullout is a war crime and constitutes collective punishment for thousands of Palestinians.''
In fact, ISR has set a pretty clear benchmark to turn the Merkava's around:
http://www.ynetnews.com/articles/0,7340,L-3268491,00.html
''Vice Premier Shimon Peres said Wednesday that the Palestinians could halt Israel's military operation in the Gaza Strip if they release Gilad Shalit, the soldier kidnapped in an attack on IDF troops near Gaza.''
BTW, here's the IDF news release on OP Summer Rains, with some (dark) video:
