Iran has cancelled plans to send a ship containing "aid" to the Gaza Strip.
I find Iran's reasoning to be very revealing. Hossein Sheikholeslam (now there's a name), Chairman of the International Conference for the Support of the Palestinian Intifada - an Iranian government body - states:
The Zionist regime has made the blockade a political issue and we do not wish to politicize this kind of humanitarian aid because the most important thing for us to break the blockade of Gaza.
So there you have it. Humanitarian aid takes a back seat to breaking the blockade. It was never about humanitarian aid. If it was Hamas would have accepted the aid aboard from the Mavi Marmara. But since it was handled by Jews...Iran and Turkey are acting in common cause. This is about waging war against Israel. Pure and simple.
