You are both misinformed and also correct.

It would be more accurate to say the current administration in Israel is only in power because it has entered into coalition with the far right. This does not make it "the most left of all possible options".

There are certainly more "mainstream" options available though I'm not sure calling them "left" would be accurate. However it is also true that the Israeli far right is not going anywhere and has only grown in power. It is not like they are a key part of the current government by accident. They may have more or less power in the future, who knows. For his part Netanyahu has embraced the far right because they were willing to support him even as he was being indicted by the courts. Recall the protests against the government in Tel Aviv not that long ago [1]. In this way he really is like Trump, teaming up with right wing forces to hold the courts at bay for personal reward.
