Rather than showing moral courage, the US is trying to compromise between Israel and Palestine to solve this quickly before Biden's visit. Abu Akleh's killing was clearly intentionally carried out by Israeli forces; countless outlets and research groups have concluded that she was killed by an Israeli sniper. She was clearly identified as a journalist, and there were several witnesses at the scene.
Though the death of Abu Akleh is tragic, critics of Israel are always quick to jump to conclusions. This investigation was a good step in deducing who killed Abu Akleh, but, unfortunately, the results were inconclusive. Israel has been completely cooperative with the investigations into Abu Akleh's death, and if the IDF was responsible, it was not intentional.
