I think the sentiment of the Palestinians is that the Arab world will rescue them.
Over the last 5-10 years things have changed considerably and support from the Arab countries isn't so simple or even given anymore. The Saudi's are not going to damage relations with the west by going against Israel. This is especially true whilst the west holds all of the cards in the region due to the depletion and isolation of Russia.
The curveball is and always will be Iran who could become involved militarily but who knows. Iran cannot however do it without Russian support and Russia is a bit busy right now.
In terms of geopolitics, this has never been a better time for the west to pressure the natural alliances in that region and align them towards western foreign policy, the defence of Israel is seemingly a key part of that.
