How did us partitioning in southwest Asia after the breakup of the Ottoman empire lead to regional conflict?

The U.S. partitioning in Southwest Asia after the breakup of the Ottoman Empire, particularly through the Sykes-Picot Agreement, imposed arbitrary borders that disregarded ethnic, religious, and tribal affiliations. This led to the establishment of nation-states that were often multi-ethnic and lacked cohesive national identities, resulting in tensions and conflicts. Additionally, the support for certain groups over others exacerbated divisions, contributing to a cycle of violence and civil unrest that persists in the region. Ultimately, the failure to address the complexities of local dynamics laid the groundwork for ongoing regional conflicts.
