Ukraine has slowed its use of Western long-range missiles against Russian military targets due to a shortage of missiles and concerns about President-elect Donald Trump's stance on the war. The missiles have had some impact, but have not changed the course of the war, according to senior NATO officials. Russia has responded with drones, missiles, and threats, but has avoided escalating military operations in Ukraine. The US and Britain granted permission for Ukraine to use the missiles, but the supply is limited and it is unlikely that Trump will provide more. Ukraine is now being more selective in its use of missiles.
