The conflict between Israel and Gaza is actually quite simple. Hammas is a political movement that sticks alot to tradition, they belive in fighting for their religion, so they belive that the war with israel is sacred and they give their lifes for it. Terrorism in South Israel is getting out of control so in a final desition the goverment decided to put an end to this conflict by hitting Gaza with all they can, the relationship between this two subjects is that terrorism is impulsed by the Hammas.
Since Hammas were elected to, in some way, rule the territory of gaza, Israel from the very begginig tried to negotiate a respectufl relationship with them, but their different belives make this almost impossible and since Israel was created in what can be know as the birth place of many religions , there should be no doubght on why evrybody fights for that small terrritory.
Icant find the thing about Oslo.
