If enough top countries came out and boycotted the Qatar WC, FIFA would have to act.
It seems as though we've reached a crossroads with FIFA- They are so brazenly corrupt, they don't even try to hide it. But everyone lets them get away with it. UEFA as well.
If there was ever a time to reign in the sleaze and corruption of FIFA, it's now. 800+ dead in Qatar, workers who were essentially slaves! All the revelations of bribes and whatnot demand action. If WC regulars like Germany, Argentina, Holland and Italy come out and say they won't play, it could prompt other countries to do the same.
Fans could do their part, too.
