I see Robertson apologized for his assassination comment, but also added:
"I didn't say 'assassination.' I said our special forces should 'take him out.' And 'take him out' can be a number of things, including kidnapping; there are a number of ways to take out a dictator from power besides killing him. I was misinterpreted by the AP [Associated Press], but that happens all the time,"
His original comments were:
You know, I don't know about this doctrine of assassination, but if he thinks we're trying to assassinate him, I think that we really ought to go ahead and do it. It's a whole lot cheaper than starting a war. And I don't think any oil shipments will stop.
I can see how the AP could misinterpret that.
