Why were the Europeans bothered about the Soviet Union at all? It was nothing to do with us. China had nothing to do with us. Why were we not building, without reference to the Soviet Union, a good society in our own countries? But no, we were all -- in one way or another -- obsessed with the bloody Soviet Union, which was a disaster. What people were supporting was failure. And continually justifying it.
