There is no way to be progressive and take the side of the Israeli government against the people of Palestine. Yes, Israel has the right to continue to exist-and no, it doesn't matter what exact words people say in accepting that, accepting the state's existence is enough- but it doesn't have the to demand that ordinary Palestinians accept having to live under indefinite Israeli military occupation until some future Israeli government, possibly decades down the road, probably after having so expanded the settlements in size that the creation of a Palestinian state has been made permanently impossible- or possibly forever, since there is a good chance NO Israeli government will ever leave the people of Palestine be.
