Not all Middle Eastern states are considered equal. I know people who have worked in Qatar and it is a very safe place relatively speaking compared to other areas in the Middle East. The people I know who have worked and lived there have had no issues and do not cower in a camp behind armed guards, if a person went there and worked there and did that then that is more of an issue with their own issues then Qatar itself.
The reality is that the sport is going to go where A) the money is. If Qatar is willing to up the prize fund and make the event more profitable for the players then that is where it is going to be. B) where fan support is. Lets face it, America and Europe both do not support pool, they have not done so for decades, and as such why the heck would you put a WPC event on in either area so that you can have empty seats in the stands and paltry prize funds due to the lack of sponsor support?
The sport has to grow somewhere, America had decades of control over the future of pool and they screwed up and watched the sport spiral down into obscurity for decades without doing anything to stem the collapse. Now they lost it to other places that are doing the job of growing the sport better then America has been able to manage. That is how it goes.
If America wants the sport back they better start proving they can actually start doing things a lot better and atm pool in America is worse off then it has been in any of the previous decades, the payouts for what major events remain are less then they ever were while inflation has further reduced the actual true value of the payouts, the stands at all events are empty, the US Open 9-ball year after year delays payment and is threatened by the American run professional organization of boycott, and American players largely skip playing in WPA events as it is and few have a legitimate chance to even compete against a WPA field. Why in the hell would the WPA want anything to do with America atm for pool? It is a dead market full of old retired former pros and top end amateur players who torture local tours and rarely ever compete against true stacked professional fields, it has no sponsorship outside of pool related companies, and it has no in person fan support and normally has empty stands during the finals of the main events.
Are you including Canada as a part of America ?
