The saddest part about all the preparations for these World Cup events and also other big events is that so many resources have to be invested into preventing terrorism attacks. The resources going into security research and implementation are a significant share of the total investment. Regrettable that the world can't just live and be in peace, but that is sadly an integral part of our lives. I think this is a huge challenge for a multi-nation World Cup when all the boarders have to be protected and the inner security isn't limited to a small area like in Qatar, but across a whole continent or even two like North and South America.
Without a doubt this is very problematic, as I see on this world cup the raise of a new trend, which is world cups being hosted by many countries as a way to reduce the costs they have pay and to take the world cup to more countries at the same time, so from now on the challenges when it comes to maintaining the security of the world cup will only increase, as without a doubt as the most important sport event around the world it is bound to be targeted by all kind of criminals.
There will always be people who want to ride on big events like this, because they are well aware that the center of attention will be directed at them when there is an event that involves many people, even this is something that will be seen by almost all countries that exist, especially those participating in it.
I'm sure they have considered and prepared as well as possible so that nothing untoward happens.
It's not easy, but when all the elements come together, it will create an atmosphere that will be comfortable later.
I also hope that there are no parties who will pit against each other or provide narratives that will make the atmosphere worse. Just like in the last World Cup, the things that made the atmosphere rowdy were people who made unnecessary narratives. It is natural when such a big event gets a lot of criticism, because after all there will always be shortcomings and it is impossible to be completely perfect, but I mean there is no need to enlarge the usual problems.
