The Ukrainian operation in Kursk Oblast is "bold, brilliant" and "beautiful," said Republican Senator Lindsey Graham upon his arrival in Kyiv on August 12, according to a LIGA.net correspondent.

"What do I think about Kursk [Ukrainian forces' presence there – ed.]? Bold, brilliant, beautiful. Keep it up!" Graham said.

The American senator said he would urge President Joe Biden's administration to provide Ukraine with all the weapons necessary "to win a war they can't afford to lose."

Graham said the process of sending F-16 fighters was taking far too long and called for the training of Ukrainian pilots.

The lawmaker added that after two and a half years of full-scale war, Ukraine is not only standing but thriving. He emphasized his admiration for the strength of the Ukrainian army and welcomed "the day when Ukraine becomes a NATO member."
