President Donald Trump‘s administration argues in its new National Security Strategy that ending the Russia-Ukraine war is a “core interest” for the United States, but it has been faced with European leaders who have “unrealistic expectations” for how it could end.

According to the document, which outlines the core principles of Trump’s “America First” foreign policy, it is in a “core” U.S. interest to “negotiate an expeditious cessation of hostilities in Ukraine,” and doing so would “stabilize European economies, prevent unintended escalation or expansion of the war, and reestablish strategic stability with Russia, as well as to enable the post-hostilities reconstruction of Ukraine to enable its survival as a viable state.”
