Don't let up now!

If Hamas is reduced to making pleas for ceasefires or "truces" in the Israeli media, then you would think that things HAVE to be bad for it: http://news.yahoo.com/s/ap/20071219/ap_on_re_mi_ea/israel_palestinians. If that's the case, Israel cannot and should not let up now. The only question I have is whether "international pressure" will mount to the point where Israel will not be allowed to finish its work.
