As good an idea as the petition for the U.S. government to build its own Death Star seemed to 34,000 people that signed it, they're gonna go ahead and pass on it.

But purely for logistical reasons, and not because the Death Star would serve absolutely no purpose. An estimate put the cost of the Death Star at $850,000,000,000,000,000. That's like three Wars on Terror, and a few Wars on Drugs, too. Pricey stuff.

It was never clear what Death Star was to be used for, but it's a safe bet that the Department of Homeland Security has something to do with it. Click here for the White House's official response, that raises some pretty compelling points in support of their decision.
