President Obama and the democrats need to prove to the GOP leadership as well as the American people that their party will restore American Honor by balancing an injustice.
If it's with a 100% certainty Prime Minister Benjamin Netanyahu will speak before a joint session of congress, then a counter of equal and just as potent needed to be taken. Formally Invite a few world leaders who are involved in the negotiations (with Iran) to come and speak as well. They don't need to reveal any sensitive information, just to lessen the damage, as well as reduce the media attention PM Netanyahu gets as well as have the spotlight on the subject of Iran by himself. Taking a stand will send messages to those for and against the talks(Iran as well) and the American people.
