I am also potentially old and unaware of Montell Fish;)
I agree that the lack of news concerning QOTSA feels alarming but they usually don´t skip Sweden during their tours to there´s still hope.
WOW usually have a co-headliner structure on one of the days so I hope that Charli and Chappell are playing on the same day which would leave us with 2 more headliners to be announced (that aren´t pop acts). Anyway, time will tell.
you have to prove intent...so yes can argue that they intend to kill Hamas and there just so happens to be a bunch of civilians there too but sh*t happens...but it's stuff that some in Israeli govt have said...and then there's telling people to move to an area for sanctuary and they then bomb it...and then there's limiting what aid can get in. All adds up.
You'll be fine - quite a few did that this year and popped a 2x2 gazebo in there - although if there's strong winds forecast they ask you to take the coverings off them.
