Take the blinkers off lads and actually read about what has happened.
I don't see why Qatar is relevant, we lost the 2018 bid to Russia not Qatar. The FIFA laws state the 2022 WC must be held in anywhere but Europe as the 2018 WC will be in Europe. The opposing bids were Australia which would be ridiculous as it's to far away from anywhere and they are a developed economy. Japan were co-hosts in 2002 so that would be a pisstake. South Korea also were also co-hosts in 2002 and America had it 15 years ago...
Qatar is an emerging country similar to the UAE, oil rich and like Abu Dhabi who got the Formula One circuit are going places. As for Sharia Law it only applies to Muslims, hotels and stuff in the country like in Dubai will no doubt allow alchohol and what-not, there are direct flights to the capital Doha 6hrs from Manchester so of the available bids its the best one for us if you were voting!
