Thus, the technological ability to detect any infectious agent rapidly and specifically are currently available. The only remaining blockades to the use of PCR as a standard tool of diagnosis are in its cost and application, neither of which is insurmountable. The diagnosis of a few diseases will not benefit from the development of PCR methods, such as some of the clostridial diseases (tetanus and botulism). These diseases are fundamentally biological poisonings by relatively small numbers of infectious bacteria that produce extremely potent neurotoxins. A significant proliferation of the infectious agent does not occur, this limits the ability of PCR to detect the presence of any bacteria.
What are the remaining blockades to the use or PCR as a standard tool of diagnosis?

The United States joined World War II in December 1941 after the Japanese attack on Pearl Harbor. On the European front, U.S. Army troops formed a significant portion of the forces that captured North Africa and Sicily, and later fought in Italy. On D-Day, June 6, 1944, and in the subsequent liberation of Europe and defeat of Nazi Germany, millions of U.S. Army troops played a central role. In the Pacific War, U.S. Army soldiers participated alongside the United States Marine Corps in capturing the Pacific Islands from Japanese control. Following the Axis surrenders in May (Germany) and August (Japan) of 1945, army troops were deployed to Japan and Germany to occupy the two defeated nations. Two years after World War II, the Army Air Forces separated from the army to become the United States Air Force in September 1947 after decades of attempting to separate. Also, in 1948, the army was desegregated by order of President Harry S. Truman.

For decades after the Second World War, any national symbol or expression was a taboo. However, the Germans are becoming increasingly patriotic. During a study in 2009, in which some 2,000 German citizens age 14 and upwards filled out a questionnaire, nearly 60% of those surveyed agreed with the sentiment "I'm proud to be German." And 78%, if free to choose their nation, would opt for German nationality with "near or absolute certainty". Another study in 2009, carried out by the Identity Foundation in Dusseldorf, showed that 73% of the Germans were proud of their country, twice more than 8 years earlier. According to Eugen Buss, a sociology professor at the University of Hohenheim, there's an ongoing normalisation and more and more Germans are becoming openly proud of their country.
Who says Germans are still afraid to be openly proud of their country?
