An American (Secretary of State John Foster Dulles?) tries to lift China with a thin and almost broken pole labelled 美蒋條約 -US-Chiang treaty. He uses a wounded Chiang Kai-shek, sitting on the small Taiwan island, to lever.
Subtitle (below the caricatures of Chiang Kai-shek and the American): Let's lift and drop this together (我们合作来撬掉它).
The US-Chiang treaty is the "Mutual Defense Treaty between the United States of America and the Republic of China" that came into effect March 1955.
