Why did President Zelensky reject the US proposal for access to Ukraine's mineral resources in exchange for military aid?

President Zelensky rejected the US proposal because he believed it lacked adequate security guarantees for Ukraine. In his own words, "I did not allow ministers to sign the agreement because it is not ready, in my opinion. It does not protect us, it is not ready to protect us, our interests." Zelensky's decision highlights his prioritization of Ukraine's national security and sovereignty amid the ongoing conflict. Despite the potential benefits of continued US military aid, he was unwilling to grant access to Ukraine's valuable mineral resources without solid assurances that would properly safeguard Ukrainian interests.
