"I welcome the decision of the allies to open up the possibility of greater use of weapons to strike these targets," NATO Secretary General Jens Stoltenberg said.
Ukraine has the right under international law to attack military targets located in Russian territory, NATO Secretary General Jens Stoltenberg said during an interview on the United News telethon July 14.
United States policy prohibits Ukrainian forces from using U.S.-supplied weapons to strike targets deep within Russia. President Volodymyr Zelensky has called on Washington to lift restrictions, saying the ability to use long-range U.S. weapons such as ATACMS within Russia and occupied Crimea would produce "an instant result."
In the interview, Stoltenberg affirmed Ukraine's right to self-defense.
There has been an attempt at a balancing act by USA and Europe, and while Europe has abandoned the idea, USA is keeping it.
The idea is that if Russia lose to much to quickly, it may destabilize Russia, and that could create a dangerous situation with the Russian nukes.
So USA was sort of in a Limbo, that Russia could not be allowed to win, but they couldn't be allowed to lose and be destabilized either.
This idea however is becoming less and less popular in USA, and there is speculation that USA will soon lift these restrictions.
I suspect they mostly didn't want their tech being examined by russia too easily, but at some point there will be so many scrap parts behind the front it doesn't matter any more.
