"Supporting Ukraine is not a charity, it is an investment in our own security," Stoltenberg said during a press briefing on Monday.
Stoltenberg also suggested that arms for Ukraine are "the way to peace."
In October, the White House requested from Congress supplemental funding of for more than $100 billion, including more than $60 billion for Ukraine, but Republican lawmakers have refused to approve the request without including substantive measures to strengthen US border security and address record levels of illegal immigration into the United States.
Western countries have been providing military aid to Ukraine since the start of Russia's special military operation in February 2022 in the amount of hundreds of billions of dollars. The aid evolved from artillery munitions and training in 2022 to heavier weapons, including tanks, advanced air-defense systems, cluster munitions and missiles later that year and in 2023. The Kremlin has consistently warned against the West's continued arms deliveries to Ukraine.
Moscow has repeatedly stated that Western military supplies do not bode well for Ukraine and only prolong the conflict. In addition, vehicles carrying supplied weapons are a legitimate target for the Russian Army.
