 This announcement of warplanes comes just days after a series of deadly Russian attacks on Ukraine, including on a children's hospital. How much of a difference can the provision of these jets make? Well, President Zelensky has said in the past that they needed around 130 to be on a par with Russia. But so far, the Allies have pledged fewer than 100, and not all of them will arrive at the same time. It is obviously, though, quite an important signal of intent, I suppose.
