Hello. You did not post the announcements that the question refers to, but I can help you, since the announcements that reflected European views at the time of imperialism, generally displayed obvious ideas about the purity and superiority of the white man and the idea that colonies are dirty places without civilization.
The idea of purity and superiority is related to the idea of the "white man's burden", which was a concept that stated that it was a duty (given by God) to Europeans to "clean up", take Christianity and dominate regions with inferior people , in this case, non-white people who lived in other countries, who were considered unclean and therefore needed to be purified by whites.
In this way, Europeans used a strong racist bias to dominate and enslave peoples of other ethnicities, promoting imperialism while claiming that this was the role that God had assigned to whites in this world.
The United States' policy of containment wasn't just military, it was ideological. Back then, we pointed out the differences between Soviet Communism and Communism around the world to weaken the power of its rhetoric, and additionally we appeared to be more successful and had a better standard of living than communists. Today, we can point out the difference between Islamic terrorism and moderate Islam, to degrade support for Islamic terrorism and make it defeat itself by containing enabling states (as Islamic terrorism is supported by enabling states) perhaps via economic incentives,and stopping our support of dictatorships, winning over those in danger of becoming Islamic terrorists. We also built up a system of allies with our containment policy regarding the Soviet Union, which helped isolate the Soviet Union. We can build up support among allies to support us in isolating states that are enablers of Islamic terrorism as well.
