Why did Eisenhower refer to communism in his message (last
paragraph)?

the answer here would be

"globalization has greatly impacted the united states and american citizens. first and foremost, globalization has spread american influence throughout the world. globalization has opened up more markets for the united states, which in effect american companies sell their products worldwide. there has been a rise of multinational corporations and their influence has greatly increased."

the first two years of american revolution was not very encouraging for the patriots since the british were far superior in sea power, arms and troops.
