bonkers. likud increased the number of seats that it holds in the next knesset. that was the whole point of calling the early election.
Likud increased its seats, but largely at the expense of the other right-wing parties. So to get to 61, he has to either align with all of the right parties and with the religious parties (who are not currently in his governing coalition), or he can leave out the hard right and the religious and join with Zionist Union and with the two centrist parties (Yesh Atid and Kulanu).
Yesh Atid and Kulanu are not really to Bibi's left on national-security issues; their focus is on domestic issues (Kulanu wants more government intervention to lower the cost of living, and Yesh Atid wants to limit the influence of the ultra-Orthodox).
Yesh Atid formerly was part of Likud's coalition; Kulanu is headed by a former Likud member; and Tzipi Livni of Zionist Union was also formerly in Netanyahu's cabinet. So the idea of national unity is not as nuts as it sounds.
