The United States has announced a $250 million security assistance package for Ukraine, including air defense missiles, armored vehicles, and anti-tank weapons to meet urgent battlefield needs. Concurrently, the Biden administration is close to finalizing an agreement to supply Ukraine with long-range Joint Air-to-Surface Standoff Missiles (JASSMs), which could significantly enhance Ukraine's capability to strike deep into Russian territory. This development has provoked a stern warning from Russian Foreign Minister Sergey Lavrov, who cautioned the US against crossing Russia's 'red lines' by escalating military support to Ukraine. The introduction of JASSMs would provide Ukraine with a strategic advantage by targeting critical Russian military sites, potentially altering the conflict's dynamics.
