Joe Biden’s long-awaited decision to allow Ukraine to use American missiles against Russian territory comes amid significant Russian territorial gains in 2024. One study shows that Russia has captured nearly 2,700 sq km of Ukrainian land this year - six times its 2023 gains. This aggressive push has strained Ukraine’s defences, despite Kyiv’s efforts to repel attacks. The destruction is immense, and Ukraine’s stretched defensive lines are increasingly vulnerable. The surprise incursion into Russia’s Kursk region initially boosted morale but is now faltering, with Russian forces reclaiming nearly 50% of lost territory. Analysts suggest that the incursion may have led to a broader strategic miscalculation, tying down its best troops and advanced equipment without significantly slowing Russia’s eastern advances. Meanwhile, the approaching second Trump administration casts uncertainty over US military support for Ukraine, raising fears of reduced aid as the war continues.
