Two things

1) For all their tough talk, the US, no matter who leads it, will not go to war with Iran. Period. And the US will do all they can to prevent Israel from doing so, too. Yes, every US candidate has to say they will; but they won't, so as far as I am concerned, question over, let's move to the next item of the agenda.

2) Are aborted infants actually viable outside of the womb?

Sometimes. Depends on many things.

Since when did Obama agree to kill surviving aborted infants?

As Pierro said, as an Illinois senator, he voted against the Born Alive Infant Protection Act.

That said, while (and you know it) I am against abortion, I am willing to concede that Obama's vote is the only position coherent with a support for abortion that comes from ideological reasons. I have to grant him that he stood by his principles there - and I quite respect that; especially given I know many other pro-abortionists wouldn't have.
