The US think-tank's latest report released on Friday said the Russians take advantage of these sanctions by launching attacks from protected areas near the Ukrainian border.
Ukrainian President Volodymyr Zelensky has asked for permission to use US weapons on Russian territory, but the US has currently refused permission to avoid further escalation.
It says the US approach to date has severely limited Ukraine's ability to defend itself against Russian attacks north of the Kharkiv region.
According to the Pentagon, America is providing weapons so that Ukraine can liberate its occupied areas, but not to attack Russia.
Ukraine aims to attack Russian targets with Western weapons more effectively than its less powerful drones and missiles.
On the other hand, Russia is warning that if the weapons of NATO countries are used against them then the war will escalate further.
