"The alternative to a two-state solution is a one-state solution. If there is a one-state solution there is going to be a big fight," said Blair, the representative of the Quartet of international mediators in the Middle East.
The idea that "a big fight" necessarily follows from the proposition that there will not be a specifically Jewish state in Palestine.
I think this idea is wrong. I cannot envision how this "big fight" is supposed to happen. I'm also intrigues by the question of why Tony Blair would believe this, or why he would say it if he does not believe it.
I can only imagine that the idea is that there is a threat that Israel is to be forced to incorporate the territory and populations of the occupied territories, that Israel will expel the Palestinians to Egypt, Lebanon, Jordan and/or Syria, which would cause a war somewhere.
I can't think of anyone anywhere that I expect to support another Israeli expulsion of Arabs now or in the future. The United States would be the most supportive, but expulsion for ethnic reasons? That violently goes against the US' claimed ideals. It is comparable to US actions with respect to the Native Americans, but those actions are universally in the US looked upon with disdain. It is doubtful that the US would support similar action today, especially overseas.
Of course, Israel's neighbors would oppose such a step. I guess this is where the war supposedly would come from. Israel would not be in a position to "win" the war, by effectively driving the Arabs out without a lot of outside support. Israel's leadership would take the level of outside support into account in the decision to make such an attempt. The question really is would Israel's decision makers believe the necessary Western support would be forthcoming. I'll repeat that I doubt it.
So does Tony Blair believe Israel's leaders would expect Western support in expelling Palestinians?
My best guess is that he hasn't thought it through. I'm sure he would never say in public that he would support an expulsion because that would be in such violent opposition to the ideals of the people he represents.
A more correct statement by Blair may have been: "If two states fails, there may be a big fight if Israel expects that it can expel Arabs with at least tacit Western support."
Could Israel expect at least tacit Western support for an expulsion? I very strongly doubt it. In which case the alternative to two states is actually a relatively peaceful transition to a negotiated one state settlement.
