I get that, and that’s the rational way of looking at it. Hamas aren’t rational, though. They’re a Salafist extremist group in a region that is continuously being bombed by the Christian West and thus not likely to accept anything with a Christian cross on it. It would be like having Perjury Greene sworn in on a Quaran or the Torah.
If part of the deal was that it HAS to be Red CROSS rather than Crescent, whomever drafted it is either incompetent or deliberately sabotaging the process.
