How many more inane slogans and Trumpian mob mantras could you fit in there.
Obama was not a war-monger. He was careful thinking and well meaning. He was highly informed and very aware of such history say as what happened in Bosnia, Rwanda, Kosovo.
He no doubt believed it was right to come to the rescue of people subjected to brutality, and crimes against humanity, of thousands disappeared in the prisons of despots, and being hideously tortured etc.
He no doubt saw it as his duty as the preeminent military power in the world to act against tyrants, dictators, gross violations of human rights, torture, mass murder, global instability and terror, world peace, crimes against humanity, wars of aggression, support of international terrorism, volatility etc.
Of course he was also aware of the incompetent, inconsistent justifications made by Bush and Blair for entering Iraq. But he was also aware Saddam was a dangerous despot who left one million dead in the war with Iran, 100,000 Kurds brutally murdered in northern Iraq, 200,000 Shia Muslims driven from the marshlands in southern Iraq, that he attempted to subjugate and brutalise the Kuwaitis in 1990 which led to the Gulf War, that he routinely butchered political opponents, and ran torture chambers and hideous penalties personally supervised by him and his family (all documented and beyond doubt).
And he was well aware of such as how Iraq repeatedly obstructed UN weapons inspectors between 1992 and 2003, their many false declarations, the biological weapons programme and nuclear development programme disclosed by Saddam's son-in-law, Hussein Kamal in 1995, the missiles designed for use in WMD wintercepted on their way to Iraq in 1995, and more.
It's always easy for uninformed cretins to rant full of self-righteous condemnation on the internet on the basis of the slogans and misinformation that they have been fed. And condemn those with actual massive responsibilities for their decisions. Done always with the benefit of hindsight, and always looking for the opportunity to make political capital, and always rushing in to fulfill their destiny as a useful fool.
