In December, FIFA's Ethics Committee said it was closing its investigation into alleged corruption in the 2018 and 2022 bidding process that awarded the World Cup to Russia and Qatar, respectively.
For now, they will concentrate on Russia, as it is their main target. Qatar is one of the most reliable allies of the United States in the Middle East region, and I don't think that they will take away the world cup from them. But there are some horrific facts that should be studied, about the conditions in Qatar. More than 1,500 laborers have died so far during the construction of the world cup venues.
