why regrettably?

""Regrettably, the two-state solution is now a fantasy. Instead, those territories will be incorporated into a Greater Israel,which will be an apartheid state bearing a marked resemblance to white-ruled South Africa. Nevertheless, a Jewish apartheid state is not politically viable over the long term. In the end, it will become a democratic bi-national state, whose politics will be dominated by its Palestinian citizens. In other words, it will cease being a Jewish state, which will mean the end of the Zionist dream."" (thanks Leila)
