From the Document: "The Biden Administration stated [hyperlink] efforts to align spending priorities with the President's Interim National Security Strategic Guidance [hyperlink] (INSSG) helped shape its FY2022 defense budget request. By law, the President is required to submit to Congress a National Security Strategy (NSS; 50 U.S.C. §3043 [hyperlink]) and the Secretary of Defense a National Defense Strategy (NDS; 10 U.S.C. §113 [hyperlink]). Officials said [hyperlink] Secretary of Defense Lloyd J. Austin III may submit the NDS in early 2022. In March, the President released the INSSG, which stated the United States faces 'growing rivalry' with China, Russia, and other authoritarian states, and would 'responsibly end America's longest war in Afghanistan.' Elements of the INSSG [hyperlink] appear to build upon [hyperlink] aspects of the Trump Administration's strategic guidance documents, including the 2017 NSS [hyperlink] and 2018 NDS. The 2018 NDS unclassified summary [hyperlink] emphasized retaining a U.S. strategic competitive edge relative to China and Russia over countering violent extremist organizations. This and the call for 'increased and sustained investment' to counter evolving threats from China and Russia marked a change in emphasis from previous strategy documents. The two approaches appear to differ in that the 2018 NDS did not address the question of pandemics or climate change as national security threats. The INSSG referenced 'pandemics and other biological risks, the escalating climate crisis, cyber and digital threats, international economic disruptions, protracted humanitarian crises,' among other threats."
