Ukraine crisis: why Russia sees Crimea as its naval stronghold

Crimea was bound to be the focus of the Russian backlash against the Ukrainian revolution. ... For more than 20 years, ever since the collapse of the Soviet Union, its rule by Kiev has been a major source of Russian resentment – inside and outside Crimea – and a major thorn in Ukraine's relations with Russia.
The Treaty of Friendship and Co-operation – by which Russia rents its naval base at Sevastopol from the Ukrainian government – is so far-reaching in the rights it gives the Russians to exercise their military powers that it is seen by many in Ukraine to undermine the country's independence.
In 2008 the Ukrainians said they would not renew the lease when it expired in 2017. But they buckled under the pressure of a gas-price hike and, in 2010, extended the Russian navy's lease until 2042.
