What does Ezekiel 31:12 mean?

Foreigners, the most ruthless of nations, cut you down and left you lying there. Your branches fell on the mountains and in the valleys. Your limbs broke off in all the ravines of the land. All the peoples of the earth left your shade and abandoned you. Ezekiel 31:12 - Modern Text Bible

(Assyria’s destruction was total, and those who depended on it were left exposed.)
