The correct answer is B) gradually decreased violence.
The US troop “surge” in Iraq in 2007 gradually decreased violence.
We are referring to the Iraq invasion by United States troops when in 2007, President George W. Bush decided to increase the number of troops in the Middle East country. The goal was to guarantee peace and security for the new government in Baghdad and some borders with Syria. Almost 20, 000 soldiers arrived at Baghdad to secure the city and help the new government to establish a democratic country despite the conflictive circumstances.
