Ok,ok read carefully.From the BEGINning there were no country as named Israel. There were just one and it was the Mandate of Palestine. Under that mandate there were more araps than jews, then jews started immigration with help of British. Araps didn't want it. This is like being an upstart who does not like the old-timers. Then British government restricted the immigration; but Jewish Agency organized illegal immigration. Both sides wants that holy grounds, especially jews no need to tell why.So you cant just say Araps caused problems and Israel reacted.
Anyway If you divide a country without making both side agree the concordat or agreement(in here the country is Palestine);sides wont acknowlage their independence and behave to the situation as rebellion or name it yourself. Problem begins with this. For jews it is independence, for araps it's rebellion/invasion.they divided Palestine and postponed the problems to nowadays. Jews used Haganah against Araps in the past, now Araps are using Hamas against Israel.
These Israel-Palestine problem is not alone. Look at Cyprus, Georgia and the others..The United Nations start to behave like its antecessor;The League of Nations.
So dont tell me Israel is right. There's no such thing as called right in politics.There are just benefits. Do you think that could Israel be founded in the first place if the other "great" countries don't have benefits from it?
