Step-by-step explanation:
The two lines in bold from the news article are related in that they illustrate President Vladimir Putin's annoyance with the United States regarding the situation with Edward Snowden. When Putin refers to Snowden as a "dubious present" and sarcastically wishes a "Merry Christmas," he is expressing frustration over the U.S. role in leaving Russia to deal with Snowden, who unexpectedly became stranded at a Moscow airport after the U.S. pressured other countries not to accept him.
Putin's comments reflect the tension in the U.S.-Russia relationship, especially concerning the fallout from Snowden's revelations which have impacted the dynamic between countries and brought about changes in foreign policy and diplomatic interactions.
