The arms sales were approved by the Biden administration in order to help defend against Iran. During his visit to the Middle East last month, President Joe Biden met with a number of regional leaders. In the last few months, Saudi Arabia and the U.S. have been hit by rockets from Yemen. Although Tuesday's approvals are for defensive weapons, they may be questioned by lawmakers who supported Biden's decision last year to cut Saudi Arabia and the United Arab Emirates off from major purchases of offensive U.S. arms because of their involvement in Yemen. The war in Yemen has led to demand for replacement limbs. A 15-year-old boy who lost his leg in a landmine explosion is changing his artificial limb. The conflict in Yemen has led to a spike in demand for prosthetics in the country. Due to the war situation in Yemen, there has been a 300 percent increase in the number of cases. The rate of motor disability was considered to be very high before the war. More than 10 percent of the people of Yemen suffer from motor injuries, which is one of the highest rates in the world. The new sales include $3 billion for Saudi Arabia specifically designed to protect itself from rocket attacks by the Houthis, and $2.2 billion for high-altitude missile defense for the United Arab Emirates. The State Department told Congress that the sale would improve the Kingdom of Saudi Arabia's ability to meet current and future threats. The department said that the missiles were used to defend the Kingdom of Saudi Arabia's borders against persistent Houthi cross-border drones and missiles. The sale would support the foreign policy and national security of the United States by improving the security of an important regional partner. Political stability and economic progress in the Middle East can be achieved with the help of the United States. In the early days of his administration, Biden promised to cut off weapons sales to Saudi Arabia and the United Arab Emirates due to their actions in Yemen.
