Why is there still conflict today in iraq?

The Iraqi conflict (2003–present) is a long-running armed conflict that began with the 2003 invasion of Iraq by a United States-led coalition that toppled the government of Saddam Hussein. The conflict continued as an insurgency emerged to oppose the occupying forces and the post-invasion Iraqi government. The United States officially withdrew from the country in 2011, but became re-involved in 2014 at the head of a new coalition.

Hope this helps ;)

industry had made the u.s. the richest nation in the world at this time. the second industrial revolution caused growth in industry and transportation, which allowed increased trade between nations.
