What are the challenges facing Ukraine in maintaining its territorial integrity?

Ukraine faces significant challenges to its territorial integrity amid resource scarcity, with reduced financial and military support compared to the Biden administration era. This limitation impedes Ukraine's ability to regain territory lost since Russia's February 2022 invasion. The political situation is particularly complex, as any deal that compromises Ukraine's constitutionally defined borders would create domestic turmoil. President Zelensky's administration would face severe political consequences, as Ukrainians strongly oppose any outcome that doesn't restore pre-invasion borders, viewing such compromises as an unacceptable national loss.
