This is closer to the real story, and it is closer to Trump’s position:
With Americans still feeling the pain and fear of 9/ 11, in 2002 the Bush administration began to build a case for invading Iraq and toppling Saddam Hussein. George W. Bush created a special office in the Pentagon— called the Office of Special Plans— specifically for the purpose of supplying him with intelligence regarding Iraq, a task previously performed by the CIA. He put his friends Secretary of Defense Don Rumsfeld and Paul Wolfowitz in charge of that intelligence reporting, creating a political “interpreting” operation that supplanted expert analysis by the CIA.
Suddenly the reports coming to the president, and leaked to the public, were full of contentions that Saddam possessed an arsenal of chemical and biological weapons, and suggested the possibility of nuclear weapons as well. Those accusations provided the ingredients for a well-orchestrated public relations campaign to lay the groundwork for an invasion with the express purpose of deposing Saddam Hussein. The justification: With WMDs at the ready, Saddam posed a threat to the United States.
After months of preparation and a demand that Saddam leave the country “or else,” on March 20, 2003, George W. Bush ordered the invasion of Iraq to begin. U.S. forces rapidly dispatched the Iraqi military and toppled Saddam’s government. In December of 2003, Saddam was captured, and three years later, executed.
Mission accomplished, at least for George W. Bush. The man who plotted to kill his father, and committed untold other crimes, is dead. But 12 years later, more than 4,000 American troops have died in Iraq— and $ 1.7 trillion have already been spent, a number that increases every day. The weapons of mass destruction George W. claimed were there, and used to justify that human and financial cost, were never found.
The people of Iraq? The horror of Saddam has been replaced by the horror of civil war, ISIS, and an entirely uncertain future.

Consider Iraq. After each pounding from U.S . warplanes, Iraq has dusted itself off and gone right back to work developing a nuclear arsenal. Six years of tough talk and U.S. fireworks in Baghdad have done little to slow Iraq's crash program to become a nuclear power. They've got missiles capable of flying nine hundred kilometers-more than enough to reach Tel Aviv. They've got enriched uranium. All they need is the material for nuclear fission to complete the job, and, according to the Rumsfeld report, we don't even know for sure if they've laid their hands on that yet. That's what our last aerial assault on Iraq in 1999 was about. Saddam Hussein wouldn't let UN weapons inspectors examine certain sites where that material might be stored. The result when our bombing was over? We still don't know what Iraq is up to or whether it has the material to build nuclear weapons. I'm no warmonger. But the fact is, if we decide a strike against Iraq is necessary, it is madness not to carry the mission to its conclusion. When we don't, we have the worst of all worlds: Iraq remains a threat, and now has more incentive than ever to attack us.

...The invasion of Iraq, he proposed, was based upon a "lie." Its advocates, he submitted, were engaged not in a mistake, but in a conspiracy. And, worst of all, George W. Bush was to blame for 9/11....Trump wants us to rig the game so he will always emerge as the winner. Irritated that Trump repeatedly gave money to the Democrats, including before the 2008 wave? Upset that Trump praised Nancy Pelosi as "terrific" when she picked up the gavel that would pass Obamacare? Annoyed that Trump called for an assault-weapons ban just as the right to keep and bear arms was being restored piece by piece? Angry that, just three years ago, he was slamming Mitt Romney for his harsh stance toward illegal immigration? Don't be. He "wasn't a politician" back then, and besides, "that's just what businessmen do." If, on the other hand, you are impressed that Trump isn't on record anywhere supporting the War in Iraq... well, that's because he has always had brilliant instincts and will make a top-notch commander in chief.
Essentially correct, but significantly lacking in many other pertinent details. Never mind, you couldn’t care less; if The Donald said it, it HAS to be true.
