have to be limited. The job,
therefore, couldn't be finished

Communist China made it clear that
it would not permit a direct assault

For fear of provoking an all-out war
with the communist superpowers.

What conclusion is BEST supported by the paragraph above?

A.) Johnson was too weak to stand up to the Communist superpowers.
B.) Johnson did not have the support of his advisers which is why he turned to southerners for support.
C.) Johnson was fully aware that he was entering war that could not be won.
D.) The choice to go to war was certainly a gamble.​
