But this story doesn't appear in the UPI archives so it can't be confirmed that it ever was reported in UPI, can it? But even normally reliable news services have published bogus stories, only to retract them when challenged. Even accepting the dubious excuse "the UPI search engine sucks" where else can this story be found? Only on screechy Jew-hating conspiracy sites. What other news stories have the two named "sources" provided? Screechy, Jew-hating conspiracy theories.
But, let's even grant that this story is true. So what? What's your point? Most countries like to keep their enemies busy with internal squabbling by boosting the opposition. If your argument is, that because Israel did this in the past, they are solely responsible for Hamas being what it is today, just doesn't wash.
BTW did you stop beating your wife before or after you were busted for selling crack cocaine?
