Money doesn't create corruption out of thin air - anyone who's corrupted by it already had to have the potential. But money does undoubtedly lead people who otherwise would have resisted their baser nature to indulge it instead.
And it very definitely provides the means for people who are already psychologically and/or morally inclined to corruption, and so is very attractive to them.
So we're supposed to believe that Israel is only at this late date "ready to risk (an) all-out war" that it in fact has brazenly and obviously been trying to provoke for months now?
Seriously?
