I never really understood why Israel is allowed an infrastructure and palestine is not.

Some of my closest friends are palestinian here in the uk and one sister is not even able to go and visit her family after the blockade of the egypt/gaza strip. .. They will not even let Gazans out of the country for medical treatment, to buy food, fuel and other basic necessities sorely missed in Gaza. Rolling power cuts continue to severely affect hospitals and health clinics and their treatment of the sick. And I believe negotiations are in progress with Jordan to cater for people in need of medical attention.
  

We all talk about freedom, human rights, and democracy but why are the voters not being heard with regards to helping palestine? And why is Israel given rights when they are in blatant violation of international law?

Why is it that exemption from punishment remains widespread for Israeli soldiers and settlers responsible for unlawful killings, ill-treatment and human right abuses. Yet Palestinians convicted of involvement in attacks against Israelis are sentenced to life imprisonment?
