The U.S. military transferred around 90 Patriot air defense interceptors from storage in Israel to Poland this week in order to deliver them to Ukraine, three sources with knowledge of the operation tell Axios. Why it matters: Getting more Patriot missiles to Ukraine has been a top priority for the Pentagon to help Kyiv defend against Russia's attacks on its critical infrastructure. This is also the most significant delivery of weapons from Israel to Ukraine since the Russian invasion almost three years ago.
