Russian President Dmitry Medvedev's visits to Venezuela and Cuba during a week-long trip to Latin America look set to irk Washington, highlighting a foreign policy challenge facing President-elect Barack Obama.
His trip to Venezuela, a key buyer of Russian arms, coincides with the two countries' first joint naval exercise in the Caribbean -- traditionally viewed by the United States as its backyard.
During his stay in Cuba, the Russian leader is likely to demonstrate Moscow's commitment to renew a Cold War-era alliance with Havana, abandoned after the collapse of the Soviet Union.
A 50-year tantrum is long enough.
