Netanyahu's speech to Congress will likely push for further sanctions on Iran, a proposal that goes against Obama’s agenda. The president has urged legislators from both parties to pause on passing new Iranian sanctions while the US and other countries carry out negotiations over Iran's nuclear policy.
Even if Congress were to pass a bill containing new sanctions, Obama would likely veto it.
Netanyahu, whose Likud Party is currently running behind the main opposition, the Labor Party, has a lot to gain, or lose, with this speech, which is viewed by some of his opponents as an election ploy. Attorney Eldad Yaniv, a former adviser to Ehud Barak, has demanded that the Elections Committee not air the speech on television networks. - CSMonitor.com
