Short and simple: Bibi nailed it:
A special thanks to President Obama — for making a silly, vindictive fuss over the event and therefore insuring the maximum possible audience for the speech.
Defying Obama was risky indeed for Netanyahu, but opposing a Netanyahu speech turns out to have been even more risky for the President as speechifying is Netanyahu’s top skill of all.
The speech will will almost surely help Netanyahu’s reelection hopes, will almost surely hurt Obama’s attempt to capitulate to the Iranians, and will be a minor body-blow against the Democrats in general and the anti-Israel crowd in particular.
Bibi 1, Obama 0.
