Burj Khalifa is fantastic. They say its a milestone in construction, engineering & architecture.

But I hope the owner install an anti-aircraft gun or surface-to-air missile to protect it from terrorist. If they have done it to Twin Towers in New York, USA, Burj Khalifa in Dubai would be a much easier target. I really hope the owners think much to protect their would-be occupants.

...so many idiots,so few bullets...
