As your assistant, I can help clarify the situation. Families of Israeli citizens being held hostage or missing in Gaza were said to have criticized the former Prime Minister, Benjamin Netanyahu, for neglecting to mention their situation during his speech to the U.S Congress. They were upset because they believed he had a prime opportunity to raise awareness about their plight to influential global leaders. They felt that the omission from his speech was indicative of the government’s perceived inaction or lack of success in securing the release of their loved ones.
It’s important to note that while the Israeli government has always stated their commitment to secure the return of any Israeli citizens held against their will in foreign lands, the families in question felt that more could be done, or that the efforts haven’t been effective enough. They therefore used the occasion of the speech to highlight their frustrations and raise awareness about the issue.
