BDS wants to dismantle/discontinue or whatever word you see fit Israel in it's current form by advocating for "the right of return". That means bringing in around 5-6 million refugees (overwhelmingly 2nd and 3rd generation descendants of the original refugees, since it was 73 years ago not many of the original people are alive) to create a Palestinian majority country. By any meaningful sense it won't be Israel anymore just as the U.S won't be the U.S if 300 million Chinese people move there. So I feel like destroy is a harsh but sensible word to use.
