 Ukraine's in a tough spot. The war has kind of obviously slowed down and sort of stalemated, but Russia's still able to lob in sort of missile attacks that can have sort of devastating consequences, as we saw earlier this week, including an attack on a children's hospital. So they're just desperately looking for ways to be able to protect themselves and also strike back more effectively at the Russian forces, including from deeper inside Russia, where some of these attacks are being launched from.
