US National Security Adviser, Jake Sullivan, anticipates Israeli Prime Minister Benjamin Netanyahu's speech to US legislators will not resemble his 2015 address, where Netanyahu criticized the Obama administration's Iran nuclear deal. There are concerns that Netanyahu's speech could strain US-Israel relations further, especially with disagreements over weapon deliveries and Palestinian state support. Despite past tensions, Sullivan expects the speech to focus on combating terrorism and achieving a ceasefire, aligning with current US-Israel collaborative efforts. The visit is viewed as a divisive moment for Democrats, with some members planning to boycott the speech while others emphasize bipartisan support for Israel.
