John Piper in Dubai: “That tower is comin’ down!”

Burj Khalifa

While filming a promo in Dubai (UAE) for the new student missions conference, CROSS, John Piper (standing in front of the Burj Khalifa tower) makes this statement:

“And that tower and this city are coming down!”

Was that a wise thing to say while standing on United Arab Emirates soil? I wonder how the Arab people would understand his remark if they saw this?
