Is there anyone in Israel running for office on the platform of "let's not assassinate terrorists"? Are these people under the illusion that they would vote for such a person, or abstain from voting if no such candidate presented themselves?
Once you vote for an assassin in your country, you lose the moral authority to denounce another country's assassinations. Romney or not.
On individual cases, you can't blame Israel for defending against hand-made rockets flying over the Gaza strip border. Similarly, you can't blame your average Palestinian for joining the resistance after an Isreali army bulldozered his village to make place for Israeli houses and theatres.
Both sides, in many ways, are equally bad. The main difference is that Israel can choose to stop colonizing, can choose to give Palestinians basic human rights to allow some sort of economy to develop. The only thing Palestinians can choose to do is to stop fighting. There's a difference here.
I don't see how all of that has anything to do with Israel being a Jewish state, except of course that declaring a single-religion state, in general, is asking for trouble.
EDIT: In a different set of comments here, it was pointed out to me that Isreal is in fact a "surprisingly secular state". I tend to believe that. So in that case, you can scratch my last line. In exchange, we all stop calling Israel a Jewish state.
Israel isn't a state for Judaism, it's simply a state for Jewish people. The set of Jewish people is not equal to the set of people who practice Judaism.
First, the settlers aren't settling in Gaza, they're settling in the West Bank. This makes the idea of rockets-as-retribution a bit strange, since relations with the West Bank are decent and they obviously undergo a lot more daily molestation than Gazans do since Israel unilaterally withdrew from Gaza.

Also, Israel is in no sense a single religion state. There is complete freedom of religion in Israel. There is an "official" orthodox Judaism there which sadly has the authority to determine if you get a real Jewish wedding among other things, but there are Muslim and Christian Israelis among everything else, and the stripe of ones Judaism is not relevant to immigration.
Who's holding the gate closed to this giant prison camp? Nobody, as it turns out, except Gaza itself. Look at questions 14 and 15 on this poll conducted by the Palestinian Center for Public Opinion:

80% of Palestinians won't give up on right of return, and they won't accept a cash buyout either. The former is as likely as America peacably returning the land to the Native Americans. The latter is an actual possibility, but what's the point if they don't want it. The Palestinian Authority doesn't want a large migration rate out, because it hurts their appeal for statehood and the argument for right of return. Hamas is responsible for turning Gaza into a prison camp, not Israel. Compare to the situation in the West Bank, where you could legitimately say there is too much Israeli interference, yet there is peace. If Gaza wants peace, they should show Hamas the door and elect Fatah. It worked for one half.
Israel has a fundamental responsibility to its citizens to guarantee their safety, and that responsibility has precedence over protecting the lives of innocent bystanders living in an enemy territory surrounded by agents who are actively attacking them. As far as this particular Gaza expedition goes, their hands are clean. This one's on Gaza.
You should try asking them how they feel about this instead of claiming hypocrisy.
