The United States brags about its political system, but the [American] President says one thing during the election, something else when he takes off… - Deng Xiaoping

If you open a window for fresh air, you have to expect some flies to blow in.

Scientists and technicians should concentrate their energies on their professional work. When we say that at least five-sixths of their work time should be left free for professional work, this is meant as the minimum requirement. It would be better still if more time were made available. If someone works seven days and seven nights a week to meet the needs of science or production, it shows his lofty and selfless devotion to the cause of socialism. We should commend, encourage and learn from such people. It has been demonstrated countless times that only those who devote themselves heart and soul to their work, who constantly strive for perfection and fear neither hardship nor disappointment can reach the pinnacles of science. We cannot demand that scientists and technicians, or at any rate, the overwhelming majority of them, study stacks of books on political theory, join in numerous social activities and attend many meetings not related to their work.

History develops in struggle, and the world advances amidst turbulence. The imperialists, and the superpowers in particular, are beset with troubles and are on the decline. Countries want independence, nations want liberation and the people want revolution — this is the irresistible trend of history. We are convinced that, so long as the Third World countries and people strengthen their unity, ally themselves with all forces that can be allied with and persist in a protracted struggle, they are sure to win continuous new victories.
