Hamas didn't have any relations with Iran at the time of the bombings, their relations started at the onset of 21st century. Plus Americans didn't pay any compensation to victims of Saddam chemical weapons attacks nor did the Iraqis (because America gave him WMD). Egyptians also didn't pay Israel anything for their invasion in 20th century. An eye for an eye will make the whole world blind.
