In the latter half of the year 2008, the country that pulled out of the Commonwealth of Independent States (CIS) was Georgia (Option 3). The decision to withdraw from the CIS was a response to the armed conflict between Georgia and Russia in August 2008, known as the Russo-Georgian War.

The Commonwealth of Independent States is a regional organization consisting of former Soviet republics that promotes cooperation and coordination among its member states. It was established in 1991 after the dissolution of the Soviet Union. At the time, the CIS included 12 member states, including Azerbaijan (Option 1), Belarus (Option 2), Georgia (Option 3), and Kazakhstan (Option 4).

In 2008, tensions between Georgia and Russia escalated into a full-scale military conflict over the breakaway regions of South Ossetia and Abkhazia, which had declared independence from Georgia with Russian support. The war resulted in a brief but intense armed conflict between the two countries.

As a consequence of the conflict and the strained relationship with Russia, Georgia decided to withdraw from the CIS on August 18, 2008. The Georgian government considered the CIS ineffective in mediating the conflict and accused Russia of aggression. The decision to leave the CIS was seen as a political statement and an attempt to assert Georgia`s independence from Russian influence.

It is worth noting that while Georgia withdrew from the CIS, it did not sever all ties with other member states. Georgia continued to maintain diplomatic relations and cooperate with some CIS countries on specific issues. However, its withdrawal marked a significant shift in its relationship with the organization.

In summary, in the latter half of 2008, Georgia (Option 3) pulled out of the Commonwealth of Independent States (CIS) due to the Russo-Georgian War and the perceived inadequacy of the CIS in addressing the conflict. Azerbaijan (Option 1), Belarus (Option 2), and Kazakhstan (Option 4) remained members of the CIS.
