The high ranking delegation which includes 60 parliament members of 12 European countriesTheir spokesman is a member of the British Labour Party. He described their visit to Gaza as
"a message of solidarity with Gaza to end the Israeli siege."
Here in the U.S. we have terrorist rights supporters, who believe that the U.S. constitution applies to foreign terrorists. That's bad enough. But at least here we don't have too many people, at least in prominent positions, who are outspoken supporters of terrorist organizations. There aren't any delegations of U.S. congresspeople visiting Pakistan, hanging out with the Taliban, and calling for prosecution of U.S. "war criminals."
The reason Gaza is under siege is because it is ruled by Hamas, a terrorist group devoted to, among other things, anti-Semitism and the destruction of Israel. Unlike Israel, Hamas deliberately targets civilians, glorifies the death of any Israelis, and does their best to perpetrate acts normally considered war crimes. Yet for some reason, a group of Europeans is in Gaza supporting Hamas, spreading their propaganda, and attacking Israel. Not surprisingly there were no calls for prosecution of Hamas war criminals, or condemnation of Hamas for launching rockets at Israeli cities.
