The irony of Chambers confession
In the book Witness, Chambers gives a detailed account of his spy activities under Russia's Communist Party. The revelations are so shocking, and he wants every person to read about his undercover activities. But, ironically, Chambers does not indicate anywhere that his revelations reached the United States thereafter! The reader knows that infiltrating government agencies in the USA is a dangerous tackle, but Chambers managed to get through without being caught.
The irony of political espionage
It is entirely satirical that the United States' intelligence information can easily leak and fall into the hands of the spies who might use that information against the USA. Chambers reveals that he had very close operatives in the Secretary of State's office, which sounds ridiculous.
The irony of the Communist Party
The Communist Party purported to be a better option for its people, but Chamber's leaked information shows that it was corrupt, war-oriented, and oppressive to its people. Therefore, communism is not any better when compared to capitalism that the Americans practiced during that time.
The irony of the economy
The economic models practiced by both the United States of America and Russia were to empower their respective people. For instance, Russia practiced Marxism which ensured that all salaried people were paid equally. On the other hand, the USA practiced capitalism to give people and businesses opportunities to create their wealth. But, ironically, these two economic models crashed and created tension among the two countries and subjected people to suffering, which is the complete opposite of the earlier expectations.
The irony of spying
Both the USA and Russia thought that spying on each other was the solution to their competing economic models because every country wanted to outshine each other. Satirically, spying on each other resulted in the cold war, which negatively impacted their economies, thus subjecting people to misery. Chambers does not indicate the merits of his spying activities, indicating that such actions were merely meant for competition, which does not benefit the common person.
