Final answer:
The State Department's decisions regarding travel to Moscow might involve denying or restricting entry due to sensitive content produced by travelers like P. and G. Breen, as suggested by historical cases such as Larry Merchant and the espionage trial of Alger Hiss. These decisions reflect Cold War-era tensions that could prompt travelers to return to the U.S. to avoid potential consequences.
Step-by-step explanation:
The decisions made by the State Department regarding P. and G. Breen's version going to Moscow are not explicitly detailed in the provided references. However, based on historical context, the State Department's decisions on travel to Moscow during tense periods, such as during the Cold War, could result in journalists or individuals like the Breens being refused entry or re-entry if they wrote material that could be seen as unfavorable to U.S. or host country interests. The reference to Larry Merchant suggests that censorship or visa issues could prompt individuals to leave the country if their work was seen as problematic. This could lead to similar situations where travelers, including the Breens, might have to decide whether to return to the United States or face potential consequences abroad.
It's important to note situations in history like the case of the NSA code experts F. Michell and William H. Martin, who apparently challenged the government's security protocols. These events underscore the delicate nature of international espionage and the intense scrutiny that individuals could face during periods of geopolitical tension. Moreover, the reference to the Alger Hiss case illustrates the serious implications for government officials accused of espionage, leading to trials and significant legal and reputational damages.
In the broader context of the Cold War and its aftermath, decisions by the State Department regarding travel to places like Moscow had significant impact on individuals' choices and actions during this era of American global power and the eventual collapse of the Soviet Union.
