The world of double standards!!!

The news that more than 40 people were killed including children and women in Gaza is not really news anymore or better put it is news but not really shocking even when video footage is shown and we see babies murdered. This true because it became the norm these days that Palestinians get murdered in cold blood and their houses are demolished day by day for no good reason. Let me correct the last sentence ‘good reason’, because apparently the world is seeing a good reason for killing children and women in Gaza and that’s why no one is speaking up their mind which may be interpreted as no objection or in fact support to the Israeli government who claim they are defending themselves against Hamas rockets. Let me ask you about the three words I highlighted in bold i.e. Israel, defending and Hamas; we all know (at least in history books) that Israel is not part of this region and it is an intruder and actually an occupying state. I do not seem to understand that an occupying force can use the word defend against the natives of the occupied land, it just does not click. Hamas is a political party with military wing in Palestine and guess what this party won the elections in Palestine so simple common sense dictates that Hamas government is the legitimate one in Palestine. But since we are in 2008 and things are a bit different I mean even climate is changing like more sun in the States in winter and more snow the Middle East so the smart folks who rule the world decided that they did not like the idea of Hamas government. So Palestinians sorry your votes do not count and you got to live with Fatah movement as government because we like them and they do not pause any threat to Israel.
We all know that Israel got some of the most advanced and accurate military systems in the world so why are they killing children and women. Are these really the targets that threaten Israel?
How come Israel who fought with many Arab states and has a big arsenal of nuclear war heads does not threatens and forms a danger to the region while Iran who support and have great relations with most of the Arab states and does not have a single nuclear war head (at least not till now); how come Iran is a danger to the region and not Israel? Furthermore, why is it ok and legitimate for Israel to develop nuclear weapons in secrecy without allowing international inspectors to visit their nuclear plants in Israel while it is not legitimate for a country like Iran to develop nuclear power for civil use or even for defense purposes?
Is it that I am just dumb and does not have what it takes to understand politics or international relations? Should I just shut up or do any of you there have a problem justifying what is going on in Gaza today? Why is the world so quite about it? Why is the UN Security Council busy issuing new sanctions against Iran while human beings are being murdered every second in Palestine?

After killig more than 120 (54% children according to an Israeli organisation) in Gaza Israel pulled out from Gaza but one Israeli official said this is just for two days while Condoliza Rice is in the region. This like saying on TV we will take a commercial break and return stay tuned.
