172 to 0. I wonder how much pressure there was to vote yes, and if some actually prefer them to stay. Having said that, it doesn't take away from the fact that it's what most want. It's just that it's so rare to see 172 to 0. Usually there are some who would vote the other way. Like a great, wonderful YouTube video. No matter how many likes it has there are always people who would thumb it down, and people ask, "Who would thumbs down such a video?"
As said before, most (if not all) of the other members of the 332 person chamber didn't attend the vote and would've voted NO. Meaning that this wouldn't have looked like such a blowout. Though the minority knew that it'd make more sense for them to protest the vote rather then to be in the chambers and lose there.
So, this wasn't a true 172-0. More like a 172-0-ALL THE OTHER NON VOTING MEMBERS WHO WOULD'VE VOTED NO.
So that Iranian troops can take over the country and other holy places for which Iran is struggling since revolution 1979. USA and other forces must quit and handover security to Iraqi forces and make sure that Iran stay away from affairs of there internal matters
If the US troops leave that region then it's going to be the last chance for stability in that region and the Iranians would have achieved what they wanted to do all along. The Iraqis are nowhere ready to take total control of their own security especially with this US -IRAN tensions currently brewing.
Plus the US isn't going to be too happy to be forced out of a region that they dumped large amounts of money into to attempt to bring democracy and stablization to. That's a pretty big slap in the face TBH.
