I loooked at that "Israeli connection" a LONG time ago,and in some detail.Some of the "documentation" is pure Arab propaganda,and some of the conclusions are (to me) inane.
I say this a non-Jew,who knows Israel and the US sometimes have conflicting interests-and are occasionally "at swords point".
For example,the notion that "Zionists" would want a war in which Israel would be the target or choice for Iraqi rocket attacks-this time with chemical and/or bio weapons does not make sense - especially when Iraq's close allies, Syria and Egypt have similar WMD programs,and would be strongly tempted to "jump in".
I have also read these reports about Israeli agents circulating about our country,prior to 9/11.I'm sure there were-and still are some-just as there are agents for a number of countries:some "friendly";some hostile.The people who originate these reports often seem to be people who want us to believe 9/11 was a covert Israeli operation-a notion Osama bin Laden and his merry men would find a bit breath-taking.
Do you ever wonder why some people want you to believe this stuff ?
