" Netanyahu … was obsessed with the nuclear issue. But it ' s too much for him. To handle this issue you have to be creative. Determined. To know how to make hard decisions, ” Lieberman stated, adding, " Netanyahu has none of those things.

After the negotiations on Iran nuclear case concluded in the Austrian capital Vienna on July 14, Netanyahu attacked the agreement between Tehran and the P5 + 1 - - the United States, Britain, Russia, China, France, and Germany, describing it as " a bad mistake of historic proportions. " Lieberman further noted that " Netanyahu is wrong on everything that has to do with handling Iran, ” emphasizing, “We need to replace the prime minister.

" Referring to the US Congress’ 60 - day period to review the agreement, Lieberman remarked, " Even now Netanyahu is not acting right. It ' s clear there is no chance to thwart the agreement in Congress. ” Although most Republicans in Congress oppose the nuclear agreement, they need a two - thirds vote in both chambers of Congress to override a possible presidential veto, and to reach that threshold, Republicans need Democrats’ support. The White House has launched a sales pitch to the Republican - weighted Congress, which remains skeptical of the nuclear accord with Iran, and has until 17 September to approve or reject the agreement.Read Also:Israel suffering its ‘worst crisis’ under Netanyahu’s leadership
