There is nothing new in this conspiracy idea. Every time a Jew somewhere in the world falls victim to a terrorist attack, the usual crowd comes out with the "discovery" of another Mossad "false flag" operation. The same happened less than 24 hours after the bomb went of in Burgas: the Internet is full of this oldest conspiracy theory: Mossad done it: just browse for "burgas airport false flag mossad" and count the hits.
But even a conspiracy theorist - not the brightest bulb on Earth - usually provides a reason for the Mossad atrocity. This time even the dimmest of the dim were able to do so - with courteous assistance from... an Israeli newspaper. Yes, Haaretz, whose scribe, Amir Oren, hastily produced the following:
There is really no need to read the article, 99.9% of its contents appears in that snapshot. Notice also the deft replacement of a "terrorist act" (or similar) by "Israeli intelligence failure". A certain contribution to the newspapermen's lexicon, for sure.
Anyway, more than half of the conspinuts have linked to the article, so thanks Haaretz and thanks Amir Oren.
