When British Defense Secretary Ben Wallace says Putin has gone “full tonto” over Ukraine, what does he mean?

When someone goes “full tonto” in English slang, he’s acting like a lunatic. The term, a former name of various subgroups of the Apache people, literally means “foolish” in Spanish. UK Defense Secretary Ben Wallace said on Feb. 23, 2022, that Russian leader Vladimir Putin had gone “full tonto” over Ukraine by invading it. Wallace told British soldiers that the British army “kicked the backside of Tsar Nicholas I in 1853 in Crimea and can always do it again.” Russian troops launched their attack on Ukraine on Feb. 24, 2022.
