Because it's not really a fight in doubt, if the former case, is it? Just an extirpation, aka as a final solution.

Here's a hypothetical to play with:

If the US withdrew all subsidies and unconditional support to the Israeli state, would they talk constructively, fight unrestrainedly, or shrug?
I imagine they'd turn to Russia or China instead, as they've done in the past. Far moreso than the Arabs, the Israelis have been skilful at playing off one superpower against another to obtain the best deal for themselves. Though there's little evidence that any of the current lot are anywhere near as adept at Macchiavelli as the masters of yore, probably a result of political flabbiness caused by a long period of guaranteed US support.

Personally, I favour the "seal them off and let them kill each to their hearts' content" solution. Neither Israel nor Palestine has anything intrinsically of value to the EU, so we might as well minimise our own contact with the conflict. If we want access to the east Mediterranean shores, we could always patronise Lebanon, which has a firmer European cultural foundation.
