Netanyahu has endured not so lurid allegations of secret meetings with Isaac Herzog to form a government, yet that outcry's died down as Herzog insists that he will not join a unity government and will be firmly in the opposition. That indicates that the right-wing pro-settler and ultra-Orthodox parties will form the first 2015 coalition of government in Israel. A two-week extension of talks by Israeli President Rivlin, to eventually form a government is predicted.
Herzog is confident as chief of Zionist Union, a centrist-left party in Israel, that Bibi will bring down whatever government he forms saying, "...Netanyahu will lead the government to hit a wall, in the end." It will likely be May before a coalition government in Israel is formed.
Benjamin Netanyahu is currently facing the agreement between the world powers, plus Germany, with Iran, over its nuclear program, while Russia is going through with a long-planned and long-held up shipment of S-300 surface to air missile systems to Iran for defense. He's facing a drop in traditional bipartisan support in the US where Democrats are tired of the lip-service to the Two State Solution(tm).
And in a threat largely seen to be real, President Barack Obama might withhold a veto on a French multilateral joint resolution in the UN General Assembly this coming September recognising the state of Palestine within the 1967 borders. This at a time in President Obama's presidency where thoughts turn to Middle East peace making; and a very fraught relationship with Bibi over the 'illegal' colonies that Israel continues to expand contrary to long-standing stated US policy.
