Well, of course the President of the United States of America does not require UN approval for any action that he may decide to take! ;-) Nor does the leader of any other country. Countries take whatever action they decide to, because they are sovereign entities, and it's their decision. Then they meet the consequences, whatever those may be...

Mussolini didn't require approval of the League of Nations to attack Ethiopia either.

Hitler didn't require anyone's approval to invade Poland or Russia.

Saddam Hussein didn't require anyone's approval to attack Kuwait (Although he did try to get a green light from Washington first, so he obviously was concerned somewhat about it...and he appeared to get just that very approval from April Glaspie, the American ambassador! She told him in so many words that the USA was not concerned about inter-Arab quarrels. Hmmmm. Interesting, isn't it?)

George Bush did not require the approval of the UN in 2003 to attack Iraq. Duh! LET'S STATE THE BLEEDING OBVIOUS, SHALL WE? ;-)    But......he sure would have liked the UN's approval to do so, wouldn't he? And he tried like hell to get it, didn't he?

That was an important part of the PR game. There's nothing that feels nicer than being able to tell your deluded public, who were silly enough to imagine that the debilitated state of Iraq in 2003 was a threat to the USA, that "we have the approval of the UN to attack Iraq". That's like tying a big red bow around the nicely wrapped package of lies you are presenting them. It's the icing on the cake.

He didn't get it. Too bad.

"any action that he may decide to take in order to defend and protect the people and interests of the United States Of America"

That's funny! And it's sad. By no stretch of the imagination was Iraq a threat to the people and interests of the USA. Not in 2003, not ever. They had no such capability. Iraq was not capable of threatening the people and interests of the USA...unless you mean by their decision to start pegging their oil sales to Euro instead of the US dollar. And if they did so decide, well, that was their business, not America's. They own their own oil and can decide what to do with it.

The real truth, then and now, was that the USA is a real and ongoing threat to the people and interests of Iraq. The USA planned to attack Iraq and did so. The USA is the one with the WMDs. The USA is the one that does to others exactly what it accuses others of doing...or planning to do to the USA.

It's the Nazi technique, right down the line. Always accuse the other guy of being THE dire threat in the world to you when it is in truth you who are THE dire threat to him, and then do to him what you said he was planning to do to you. The big, giant lie. And your people will believe it. After all, the Germans did.
