how to paraphrase below paragraph:
Cohen argues that while some forms of diasporic involvement may be motivated by nationalist sentiments, it is essential to recognize that diaspora communities are complex and dynamic, and their engagement with their homeland is shaped by a variety of factors, such as their history, political context, and relationship with the state. Cohen does not regard diasporic engagement as just a sort of long-distance nationalism; rather, he views it as a phenomenon with several facets that demand thorough research and comprehension.
