The Department of Homeland Security is a Cabinet position that was created in 2002, out of response to the terrorist attacks of September 11, 2001.
Here is the excerpt from A Rumor of War which best illustrates Vietnam's uncomfortable climate:
<span><em>The tedium was occasionally relieved by a large-scale search-and-destroy operation, but the exhilaration of riding the lead helicopter into a landing zone was usually followed by more of the same hot walking, with the mud sucking at our boots and the sun thudding against our helmets while an invisible enemy shot at us from distant tree lines.</em></span>
You didn't list options, but I'll suggest an item which famously occurred during Warren G. Harding's presidency:
<h2>The Teapot Dome Scandal</h2>
This was a scandal in which one of President Harding's cabinet members illegally leased oil reserves. President Harding was not directly implicated in the scandal, but was affected by it. After President Harding transferred supervision of the naval oil-reserve lands from the navy to the Department of the Interior in 1921, Secretary of the Interior Albert Bacon Fall secretly gave Harry Sinclair of the Mammoth Oil Company exclusive rights to the Teapot Dome reserves in Wyoming. He granted a similar deal to another oil company executive. The secret leases came under Congressional investigation. Congress directed President Harding to cancel the leases, and the Supreme Court ruled that Harding's transfer of authority to Interior Secretary Fall had been illegal. The whole affair took a toll on President Harding's health. He died in office in 1923.
Confucianism or Buddhism. C or D. Your best bet is Buddhism if the question doesn't include to select more than 1 answer.
