Maybe you need better reading comp lessons?

Those "buts" are because while hamas is at fault, they are not the only ones at fault. Without that but, israel would be posed as the sad victim. They are equally guilty of this terror attack.

They created hamas. The only victims here are the festival goers, and the palestinian civilians that israel will kill using hamas as a justification.

Hamas isnt being excused. Its being contexualized.
