Israel/Palestine

The accused is not a recognized foreign diplomat for the United Nations. He's a local worker.

The accused has a right to a trial at which time each side can present their side of the story.

As for the UN's investigation, I give it as much credibility as you and Mondoweiss do to any investigation by the IDF. Heck, the UN still hasn't explained the mysterious missile stockpiles Israel found and destroyed in the UN schools during the last Gaza war.

The UN wants this to go away quickly and quietly because they work in Gaza, and since Gaza is run by Hamas, even the elements of the UN not directly sympathetic to Hamas, have to work with them. They are also afraid that a public trial could impact donations to the region from Western and some Arab governments and groups (more so than most of the money already pledged and never delivered.)

However, you are correct that this arrest will indeed impede UN development and aid activities in Gaza. If Hamas doesn't get their cut and able to divert money and material to their terrorists efforts, they will not allow the UN to operate efficiently, or in some cases, at all. You should direct your ire at the Hamas for they apparently care far more about killing Jews than the welfare of their own people.
