Before saying "Palestinians" are being killed, we need to know what is the definition of the term. MOST of tghiose being killed today in Gaza are second and third generation nomadic Bedoin now stateless persons forced by Syria, Jordan, Eygpt, and Saudi Arabia to live in the area now called "The Gaza Strip. This because the attack on Israel, the day it was offically formed, by ARAB forces including those living in Gaza who REFUSED to accept citizenship on the new state of Israel, and in fact, took up arms to kill all Israelis.
These same "Palestinians" are NOT claiming that theuy have the right to live peacefully in Gaza, but that they have the right to ALL ISRAEL, and to KILL OFF the Israelis living there. And, BTW, it is not ISRAEL keeping these peeople in Gaza but the ARAB and Persian nations that REFUSE to integrate these sons and grandsons of the pawns in the 1948 attack into their own countries. Indeed, Jordan killed off a large chunk of the contingent living there as soon as they tried to exert political influence.
I hate to use wiki, but here is a link

Anyway, the Israelis have as much, maybe more clain to the name "Palestinian" than any Arab Bedoin, further, had the Arab Nations absorbed the Bedoin "Palestinians" and offwered , at least, the GRANDCHILDREN of those who attempted to murder the Jews in 1948, THERE WOULD BE NO GAZA and therefore, at least this skirmish in the last 60 years of on again off again war would not have happened.
