Which would get them exactly back to where they are today, which is why I'm not sure how this is supposed to be a threat. Consider this duly filed under We're Losing To A Bunch Of Fucking Clowns:

A senior Hamas official in the Gaza Strip warned Israel that any attempts to rescue abducted Israel Defense Forces soldier Gilad Shalit would spur the Islamist group to kidnap more soldiers, the pan-Arab London-based newspaper Asharq al-Awsat is reporting in Wednesday editions. "If Israel tries to rescue Gilad Shalit, we will kidnap more soldiers," Mahmoud Zahar told the newspaper. The Hamas official was reacting to reports that Israel was threatening to take "various active measures" should Hamas continue to delay talks over the captive soldier. Israeli officials sent this message to Hamas via an Egyptian mediator last week. The Hamas official added that Israel has exhausted all military means at its disposal to win the captive's release with no results.

Yeah, I dunno if that last part is true. But more importantly - this seems like an interesting and underplayed geopolitical tidbit:

Israel is expected to free the 40 Hamas Palestinian parliament members held in Israeli prisons, as part of a deal to release Shalit. However, if Israel takes this step before the end of 2009, it is expected to bring Mahmoud Abbas' term as Palestinian president to an early close in a legal sense, though not necessarily in practice. The legislators' release means that Hamas will once again have a majority (74 out of 132) in the Palestinian Legislative Council.

Here is Secretary Rice last month praising Israel for showing good will by releasing prisoners. And here is Secretary Rice last month insisting that Abbas must be at the top of the PA. These are two positions, I suggest to you, that might not be entirely absent of tension.
