I want to know the answer to the following question:
Why was the US naval blockade not feasible?
All the background I'm provided with is that "As an initial response, Truman called for a naval blockade of North Korea, and was shocked to learn that such a blockade could be imposed only 'on paper', since the U.S. Navy no longer had the warships with which to carry out his request.". Is that enough to answer the question?
Answer: yes
