If I recall correctly, in their original bid I believe Qatar said they would have no issues holding the WC in it's regular months. I think they were going to build air conditioned stadiums or something like that.
The moment they went back on that and requested a move to winter, FIFA should have taken it away and awarded it to the US, who finished second in voting. For some reason FIFA had no issue with moving it to winter, and I am pretty sure all the club teams complained loudly about it.
With those stadiums being built with slave labor, FIFA should take it away. It would make a great statement to the rest of the world. On the one hand, FIFA is seems to be trying to curtail racism and sexism in the sport, but turns a blind eye to an entire nation using slave labor to build stadiums. There are plenty of options to move the WC to, and there are four years to get things ready. Makes no sense.
