You may assume the left is cheering on Netanyahu’s Likud attackers. Therefore, protecting Netanyahu now is protecting Israel. Without his leadership, Likud and the Right will crumble and succumb to a Gantz-led drive for a Palestinian Arab State in the ‘West Bank’.
Before you kick a hero of Israel when he’s down, ask yourself why they are attacking him. The answer is that he is the only thing standing between Israel and a Two-State solution leading to no-Israel. So, stick with Netanyahu until the bitter end, or the end of Israel will come to pass before you know it.
