“Crimea was in Russian hands at the beginning of this war. Therefore, if you really think that Putin will have to give up Crimea as a condition for achieving peace, then you are crazy,” he said in a video message following an interview with the Russian leader.
Carlson added that attempts to weaken Russia make no sense.
Earlier, Russian Foreign Minister Sergei Lavrov, during a speech at a meeting of the UN Security Council, said that Russians and Ukrainians live in Crimea in peace and harmony.
Crimea became a Russian region after a referendum took place there in March 2014: the majority of residents were in favor of reunification with Russia.
The Kremlin has repeatedly emphasized that Crimea is an integral part of Russia and claims to Russian territory will receive a proper response.
