saddam hanged-right or wrong?

Saddam was a despot who committed many an atrocity, but he was a deposed ruler of a country, a soverign nation that was attacked and conquered because of lies, whether intentional or un intentional, there was gross interference in the internal matters of a soverign nation, without any cry for help from that nation. The entire sordid affair has left a bad taste in the mouth of most humans in the world and azblack mark on the history of 2 great nations (Iraq-one of the cradles of civilizations and the US, one of the freest countries in the world). I don't think any president of the US will be beleievd by too many people.
