Germany has been arming terrorists with chemical weapons, chlorine gas and chemical bombs

[Hack-Hook]

Agree to the part that ever since fall of Saddam and Iraqi army, there's no independent Iraq.

Disagaree to the part that Saddam was hanged by some state employees.
Drama that unfolded at Saddam's gallows was evidence enough to show that he was hanged by the usual haters.
Everyone in Iraq knows, Muqteda Saddar men hanged Saddam.

Well let look at the fact that were he hanged .

The execution took place at the joint Iraqi-American military base Camp Justice, located in Kazimain, a north-eastern suburb of Baghdad.

And who ordered his execution

Supreme Iraqi Criminal Tribunal
The Iraqi High Tribunal (IHT),[1] formerly the Iraqi Special Tribunal[2] and sometimes referred to as the Supreme Iraqi Criminal Tribunal, is a body established under Iraqi national law to try Iraqi nationals or residents accused of genocide, crimes against humanity, war crimes or other serious crimes committed between 1968 and 2003. It organized the trial of Saddam Hussein and other members of his Ba'ath Party regime.

The Court was set up by a specific Statute issued under the Coalition Provisional Authority and now reaffirmed under the jurisdiction of the Iraqi Interim Government. In 2005 it was renamed after the constitution established that "Special or exceptional courts may not be established."[3] The Transitional Administrative Law (TAL) promulgated by the Iraq Governing Council before the restoration of Iraqi sovereignty preserves and continues the Iraq Special Tribunal Statute in force and effect.

Let see who were the judges .

Trials are heard before a panel of the five Trial Judges, who conduct hearings, pronounce judgements and impose the sentences, without using a jury. There is also a separate Appeals Chamber, with nine judges, a prosecutions department and an administrative department.

Then tell me where in this procedure moqtada Sadr is placed ?
He was sentenced to death for killing 148 Shia for fun of it.
That was the official report well the real reason can be found in Saddam letters itself when less than 48 hours before his execution he asked Iraqi people not to hate the government but invading countries specially USA .
He was a figure head in Iraq and a danger USA and qualition plans for Iraq. We had no problem with him after the end of war.

and also we have this

In a separate statement, Saddam's American defense lawyer called the execution "an unfortunate display of arrogant aggressor's injustice by the United States of America under the leadership of American President George W. Bush. It sets back achievements in international criminal law many decades and sends a clear message to people all over the world that the United States' aggression cannot be stopped by the law. It is truly a sad day for international justice and sad beginning to a new year."[44]

And this is Sadr stance on the videos

In an interview with La República on 19 January 2007, Muqtada al-Sadr said that the people who were in the room during execution were "people paid to discredit him" and the purpose of the unofficial video was to "make Muqtadá look like the real enemy of the Sunnis."[46]
