Daily Cuts - Would allowing Ukraine to use long-range weapons pay off?

As the US and Britain discuss allowing Ukraine to use Western weapons to strike deep within Russia, some US officials are deeply skeptical that doing so would make a significant difference in Kyiv's battle against Russian invaders.
