The Role and Implications of the United States of America in the Russia-Ukraine War (2014-2024)

Abstract

The influence of the United States in the Russia-Ukraine conflict from 2014 to 2024 is examined in this study. The specific objectives include military assistance, economic sanctions, NATO defence expenditure, and the resulting effects on world oil prices. With around $66.5 billion given since February 2022, U.S. military support to Ukraine increased dramatically, so improving Ukraine's defence capacity. Descriptive statistics and content analysis techniques were adopted to assess American engagement. Concurrently, the United States issued extensive sanctions aimed at Russia's energy sector, mostly impacting over 180 linked corporations like Gazprom Neft and SURGUTNEFTEGAS as well as big companies like with the energy price index peaked at 183.07
in February 2025, up from 100 in 2016, these penalties helped to drive a global energy price spike. From 1.43% of their combined GDP in 2014 to 2.02% in 2024, NATO defence spending also saw a significant jump as European members and Canada invest a combined total topping $485 billion in 2024. Results revealed Std. Dev. = 14.7% in aid, indicates that a structured aid mechanism
conditioned on performance and crisis thresholds would ensure consistent support (MEHA); moderate fluctuation in sanctions (Std. Dev. = 4.66%) indicates stable pressure (SRIC); the high variation in NATO spending (Std. Dev. = 12.64%) indicates inconsistent commitments (MSN); despite USGE’s stability (Std. Dev. = 1.41%). Findings show that invasion tactics such as reflagged tankers and concealed routes weaken their impact (USGE). According to the study, U.S. military and financial support greatly enhanced Ukraine's defence capacity. The study recommends the creation of a multi-aid structure under open control to guarantee constant support for Ukraine's defence and humanitarian needs and apply coordinated secondary penalties aiming at companies supporting Russia's sanction avoidance.
