In order to avoid Serious injury or death when operating Firearms as well as other similar weapons such as AR artillery pieces and flamethrowers, the universal rules of firearm safety was developed.
These were retired pretty quickly, though, mostly because when you put the words makeshift and flamethrower next to each other, you're bound to run into some problems eventually.
Something similar happened in 1916 when a French flamethrower regiment was conducting an assault on German positions, when a gust of wind blew the burning fuel back on the operators, killing 25 of them.
Since the first world war, flamethrowers were part of the arsenals of many nations, playing an important role in the trenches of the western front, the jungles of the Pacific theater, and many other places across the world.
So the the taking to the trying to get the mosquito with the flamethrower is not is not going to be a detriment to the United States when it comes to these negotiations and getting people to the table.
And right now, the incentive structure to be the flamethrower, to be the loudest in the room, to be the one that gets on the media outlets, is stronger than the one to be the other one.
