Bibi has already backtracked from his earlier statements:

To be fair, he was careful in his formulation both at Bar Ilan and this week. This week, he didn't say 'I oppose a two state solution', but rather 'during my tenure as PM there won't be a Palestinian state', which instead of a policy statement could be a prediction about the disarray and total powerlessness of the current PA leadership... and is almost certainly correct. Similarly, during his Bar Ilan speech years back, he said he supported a Palestinian state, but couched it in all sorts of restrictions to make it palatable from a security and political perspective.
So... same old, same old.
Oh, and Lewk: I'm happy that the vast majority of Israelis disagree with you.
