I don't have the slightest doubt that in early 2003 you were a cheerleader

for invading Iraq.
Nobody was just "neutral" about it.
I was. My reasoning was different. I saw it like this:
Saddam Hussen was a major funder and supporter of terrorism worldwide, particularly Islamic-based terrorism. There is plenty of solid proof of that.
Saddam Hussen was harboring known and wanted terrorists within Iraq. Again, 100% accurate and factual.
Saddam Hussen had terrorist training camps set up within Iraq to assist in exporting terrorism. Those were discovered and documented during the invasion of Iraq.
Al Queda was a terrorist organization based on Islam, at least in good part, and needed a safe base of operation to carry out its acts. They chose the Islamic state of Afghanistan run by the Taliban for that.
After 9/11 we were going to destroy Al Queda. That meant invading Afghanistan to do so.
Al Queda would try to survive that destruction, and one means they would seek is other safe places they could continue to operate from.
Iraq was clearly one of those places. Al Queda had an open invitation to move and operate there but chose not to because they deemed Saddam's government and Saddam himself insufficiently committed to Islam religiously for their tastes.
With the US invading Afghanistan, but not Iraq, it is very likely that some of Al Queda, including possibly its leadership like Osama bin Laden, would have fled to Iraq for safety putting their religious differences aside for the moment.
This would result in the US having to invade Iraq to defeat Al Queda and we end up at the same result.
Thus, I had no qualms about us crushing Iraq and Saddam Hussen preemptively.
