The invasion of Iraq had heavy support from both Republicans and Democrats. The majority of Democrats in the Senate supported the invasion. Overall public support for the invasion of Iraq prior to the start of the war was higher than support for the 1991 Gulf War before hostilities began.
In 1991, public support and support in Congress was much more divided about going to war at the time. In the aftermath, future presidential hopefuls like Senator Sam Nunn payed a price for not voting to support the first Gulf War.
Today, support for Operation Iraqi Freedom is split with those still supporting in the low 40s, and those against it in the high 40s. You get reverse results when you ask the veterans who fought in Iraq, with a very slight plurality or majority supporting it.
But that was the same with World War I and Korea. After those conflicts were completed a slight majority were against them for many years. But over time, the evolved into a majority saying involvement in those conflicts was a good thing.
Iraq will likely end up the same way. At the end of the day, there was nothing good about Saddam. He was evil and had caused everyone problems for decades. Few people will be willing to defend or stand up for Saddam in the years ahead. Iraq's standard of living is increasing, ahead of Morocco now. The murder rate in Iraq for 2018 was less than the murder rate in California for 1990. Kuwait and Saudi Arabia are much safer with Saddam gone. People become frustrated with the unexpected cost and duration of the conflict at the time, but ultimately in the long run its likely most people will judge that It was worth it.
Most Democrats in Congress voted against an Iraq invasion.
That is an undeniable fact
Iraq was a decision of George W Bush
If it was a success, he would deserve credit. Since it was a dismal failure, he holds the blame
NOT in the United States Senate. In the United States Senate, a majority of Democratic Senators supported the war.
Its only in the House Of Representatives, typically where you will have younger, less experienced people, where a majority of Democrats were against the war.
The war in Iraq was a success in every relevant respect. Saddam was removed from power. A new government was successfully put in place. That new government is not a threat to its neighbors and is not interested in the production and manufacture of WMD. Stability inside the country was initially a problem, but that seems to be in the past now. In 2019, the government in Iraq is viewed primarily as stable and respecting most of its tribes and ethnic groups. It is not a threat to Kuwait or Saudi Arabia. It is seen as a possible bridge between Saudi Arabia and Iran in terms of relations and resolving conflicts and political differences.
United States losses in Iraq were a tiny fraction of what it lost in similar sized wars like Korea, Vietnam, World War I, and World War II. 3,500 killed by hostile fire in Iraq compared to 48,000 killed by hostile fire in Vietnam. Total civilian casualties are also much lower at around 200,000, mostly as a result of terrorist bombings and insurgency. Much lower than the millions of civilians that died in the other wars. 16 years after the invasion, Iraq is a thriving developing country with a murder rate lower than California's murder rate in 1990. It is not a threat to any of its neighbors unlike Saddam's Iraq. The Iraq war has been a success by any measure. But all wars have their cost. But the cost have been light relative to similar wars and conflicts in the past.
In addition, total US defense spending as a percentage of GDP averaged less than 5% during the whole period from 2001 to 2019. During the peacetime of the 1980s, U.S. defense spending averaged 6% of GDP. So the financial strain on the country and the economy has been much less than similar size wars the United States has engaged in the past.
