The video is grainy footage of IDF doing manly and powerful work to destroy their enemies, with a really catchy dance tune playing behind it.
Here are some quotations from the lyrics (translated across the screen as it plays):
[K]now that there's no despair around here at all...
It's already been sentenced from above that this is your end
...you have lice in your beard...soon you'll be out of here
[W]e will send you back to allah with all the hezboallah
