More symbolic than anything, but still important as a major European coalition leader. Germany hasn't given long-range weapons to Ukraine thus far.
The US previously announced it was allowing US weapons to be used against Russian territory near Kharkiv in response to the Russian offensive to take the city.
Italy and Spain are the main remaining holdouts. But the most important allies that have supplied long range weapons have greenlit use of their weapons against Russian territory.
I do like how absurd this latest round of logic is in particular. We allow you to use the weapons to repel the Russian invasion of Kharkiv. Let's pretend like somehow that hasn't been occurring since the beginning from across Russia.
