David Axelrod on CNN.

Twitter users reacted harshly to a slew of petty and snide remarks from former President Obama Senior Adviser David Axelrod, who criticized Israeli Prime Minister Benjamin Netanyahu’s speech to Congress on Tuesday about the Iranian nuclear threat.

“Iran is a grave issue,” Axelrod tweeted. “But make no mistake: Bibi’s speech is more about an ‘existential threat’ to his own electoral prospects in 2 weeks.”

Axelrod further tweeted: “Speech broke no new ground nor offered realistic path short of war. But apocalyptic language & GOP cheerleading tailor-made for his base.”

Responding to Axelrod’s assertion that the speech was an electioneering effort aimed at Israeli voters ahead of the country’s general election, some Twitter users were livid.

“@davidaxelrod implies Israelis wrong to view nuclear Iran in ‘apocalyptic’ terms. Astounding,” wrote Noah Pollak.

Twitter user Allen said: “@davidaxelrod I can’t imagine how he could use apocalyptic language when discussing nukes in the hands of a country sworn to his destruction.”

“@davidaxelrod Not surprised that you didn’t recognize true leadership nor understand the historical significance of this speech. Sad….,” another said.

In an interview with Reuters on Monday, President Obama challenged Netanyahu’s objection to the nuclear deal currently being negotiated between Iran and world powers, claiming that there is no viable alternative to seeking a temporary freeze on Iran’s nuclear program. Netanyahu has consistently called for an arrangement that sees Iran’s nuclear capability completely terminated, a sentiment he repeated in Congress on Tuesday.

Other Democrats adopted a similar tone to Axelord. House Minority Leader Nancy Pelosi claimed: “I was near tears throughout the Prime Minister’s speech – saddened by the insult to the intelligence of the United States as part of the P5 +1 nations, and saddened by the condescension toward our knowledge of the threat posed by Iran and our broader commitment to preventing nuclear proliferation.”
