And if he really were doing undercover stuff then the stamp from Israel says something is off and there are definite pieces missing (at least to me). Anywho who has/wants to/is contemplating/etc. travel to anywhere with ANY ties to someplace that has Arab connections (which could include all of the Middle East, northern/eastern Africa, and SE Asia) knows you NEVER get a stamp from Israel in your passport. It's asking for trouble, and in MANY countries can even keep you from entering (or at least getting a visa for more than transit through the country).
For someone who has traveled as he supposedly had to so many places, how on earth would he never have known that? Besides they are very good about putting the stamps on another piece of paper if you do go through Israel. It just seems very odd...that's (the stamp from Israel and the mentioning Israel and his times there openly to many people like new articles are beginning to mention) almost like asking for trouble in that part of the world...at least from my experiences there.
