As a parasitic entity, Israel needs to attach itself to a host like the US and use it to feed off American tax payers.
If it is left on its own, the Apartheid state will shrivel and die; so it is vital that Israel projects a positive image around the world and does not become too expensive or bring the host too much into disrepute.
Otherwise the host might one day decide that the price for allowing the Israeli entity to suckle billions of dollars from its breast might be too high and abandon it to its fate.
Hopefully this will be soon.
