The Iran-backed Houthis launched a ballistic missile at Israel, targeting the population during the morning hour. Despite a week of US airstrikes, the Houthis remain undeterred and have vowed to continue their operations. The US says it will hold Iran responsible for the Houthi attacks, but airpower alone may not be enough to win the war. It is unclear if the US will fly missions from nearby bases due to the fear of Houthi retaliation. The difficulty of tracking down ballistic missile launchers and the Houthis' ability to hide the missiles raise questions about the future of the campaign.
