 In January 2009, Congressman Dennis Kucinich sent a notice to Secretary of State, Dr. Condoleezza Rice, that Israel’s actions in Gaza since December 27, 2008 may constitute a violation of the requirements of the AECA.The AECA requires that each nation that receives a shipment of arms from the United States must certify that the weapons are used for internal security and legitimate self-defense, and that their use does not lead to an escalation of conflict.However, the AECA does not define "internal security" or "legitimate self-defense."
