You're telling me that a constitution is not, by definition, an ideological document?
I don't understand how you can live in this world where you recognise that the parties and people that make up the state apparatus are ideological but the state itself is not. There's no magical step where the functioning of these explicitly ideological people somehow becomes non-ideoligical. Believing otherwise is itself an ideological position, namely a liberal one.
Just because different lib parties have disagreements doesn't mean they aren't liberal. Almost without exception they 'recognise Isreal's right to defend itself'. They all implicitly, if not explicitly, support a settler-colonial apartheid state. And what would be more fitting than liberals supporting such a state? When it was liberal thinkers like Locke who's theory served to justify the British settler-colonial project in the Americas.
I suspect a some of the other players in the region that are taking the position of intervention if Israel starts a ground offensive in Gaza are doing so because they hope or believe it is unlikely the IOF will want to go into Gaza.
Obviously such a scenario would be terrible for the Palestinians and it is good that it is clear such an act would come at a high cost to the zionists. But realistically, the IOF would suffer heavy casualties regardless of the involvement of anyone other than the Palestinians. Israel has to understand that, one would think.
What's more, the addition 'if Isreal starts a ground offensive into Gaza' allows for Arab nations and groupings to not get involved further if Israel is content to just bomb the shit out of Gaza.
What I'm getting at is that I wouldn't be surprised if these countries, while genuinely sympathetic towards Palestinians, would very much prefer not to get involved directly and will look for excuses not to if things escalate. Ofcourse this is all speculation over things that still feel up in the air.
