The online poll showed Britain with the highest number of militant votes followed by Russia and Germany; Italy and the United States were tied for fourth.
Another poll that surfaced on Twitter asked Daesh militants a similar question.
"What will be the next attack by the Islamic State?"
In that poll, ISIS fighters were able to choose between Italy, France, the Netherlands, and Belgium. It had a total of 103 responses, and the results were only available to voters. ISIS supporters responded to the online polls by filling Twitter with hate filled threats of violence, reports Vocativ.
"Britain has taken all precautions, the Caliphate doesn't stop at barriers."
Other defiant Daesh militants used Twitter to chime in with their own threats, reports the Daily Mail.
"The Islamic State will attack London, Washington, Rome and all the infidels' capitals."
Another jihadi taunted the West with threats of his own.
"The Crusaders are blundered and confused. Yesterday Paris, today Brussels, and they don't know where will be the next attack."
This isn't the first time the Islamic State has used social media to poll supporters and ask them to vote on its sick and twisted methods. When a Jordanian pilot was shot down over ISIS caliphate territory in December 2014, Daesh created the appalling hashtag #SuggestAWayToKillTheJordanianPilotPig to ask for different ways to kill their captive.
He was eventually burned alive on film.
