For example, US is their biggest enabler and supporter… So perhaps they can allow Israel to exist within US.
They can have Oklahoma and Kansas. They’ll have many times as much lebensraum and the ones currently in charge there have proven to not be responsible enough to run a state.
As a bonus, there’s hardly any Muslim-Americans living there now, so evacuating them all to other states of their choosing before Israelis arrive to potentially endanger them should be completely doable!
