In the end  IS suffered its most decisive defeat and watched their self-proclaimed caliphate evaporate in Iraq  then in Syria as Kurdish-led forces retook Raqqa  ISâs urban stronghold there.
The battle for  Raqqa  which became  ISâs operational base in Syria  had a different feel to it as U.S.-backed Kurds and Arabs in the Syrian Democratic Forces (SDF) tightened their siege.
In the weeks before  Raqqaâs  fall in October  young female SDF fighters faced off against hardened militants and suffered losses. But that did not curb their enthusiasm and some said they would eventually like to join Kurdish PKK militants in Turkey and help advance their 33-year-old insurgency there.
After ISâs defeat in Raqqa   Raqqa residents  formed a council to run the city but  they  had no budget when it was first set up  just residents streaming into  their  tin  run-down headquarters demanding everything from instant jobs to getting  their  damaged farmland back.
The Kurdish groups who led the fight against Islamic State in its former capital  Raqqa  must now navigate a complex peace to avoid ethnic tension with the cityâs Arab majority and to secure critical U.S. aid.
So  life for  Raqqa âs victors will remain fraught with risk.

Behzad Mesri  was charged in a seven-count indictment with computer fraud  wire fraud and other crimes.  He  is believed to be in Iran and likely beyond the reach of American authorities  but federal prosecutors and the FBI scheduled a lunchtime news conference to discuss the case.
Bill Sweeney  assistant director in charge of the FBI's New York field office  said that  Mesri  "lurked in the alleyways of the Internet  identified the vulnerabilities of his victim  and pickpocketed their information from thousands of miles away. After he had successfully identified their proprietary secrets  he held their future for ransom. Today's charges show that international cybercriminals are never beyond the reach of U.S. laws."
 Mesri  was a self-professed expert in computer hacking  court records said.  He  had worked previously âon behalf of the Iranian militaryâ to hack military systems  nuclear software systems and Israeli infrastructure.
 He  was known online as Skote Vahshat  a hacker pseudonym federal prosecutors said  Mesri  used to deface hundreds of websites in the United States and elsewhere around the world.
