Santa's new little helper

Don't worry kiddies.Santas got protection now.
The U.S. military has decided Santa needs protection so they've ordered a squadron of F-16 fighter jets to escort Santa around the world.
Why and who does Santa need protection from?
Stumped
Merry Xmas and to all a good night.
Many thanks to my little helper,I'd name you but I don't want the NSA to know your real identity.
They've probably hacked Santa and know who's been bad anyways....
