Julian Assange, the founder of the WikiLeaks web site that leaked 250,000 classified U.S. documents, has accused America of spying on its allies. The contents could cripple America's foreign policy.

Condemnation from high-level officials stretches from military officials to lawmakers on Capitol Hill.

"The people who are leaking these documents need to do a gut check about their patriotism," Sen. Claire McCaskill, D-Mo., said on "Fox News Sunday." "Frankly, it's coming at a very high price."

The documents don't reveal anything top-secret, but they do show behind-the-scenes diplomacy at work - something the U.S. would rather keep private.

Some of the embarrassing characterizations include calling Russian Prime Minister Vladimir Putin an "alpha dog" and French President Nicolas Sarkozy the "emperor with no clothes."

Still, the real damage may be to those the U.S. considers allies in the fight against terrorism.

Afghan President Hamid Karzai is described as "driven by paranoia," while Yemen President Ali Abdullah Saleh is shown to have agreed to lie about U.S. air strikes in his country.

Documents also show Arab leaders privately taking the same stance as Israel in opposing Iran's nuclear plans.

Officials believe the documents could harm how the U.S. conducts business in the future.

"We live in a world where just a little bitty piece of info can be added to a network of info and can open up an understanding that just wasn't there before," Adm. Mike Mullen, Chairman of the U.S. Joint Chiefs of Staff, said on CNN's "Fareed Zakaria GPS" Sunday.

U.S. envoys, including U.S. Secretary of State Hillary Clinton, have been working on damage control.

With the latest leaks, Assange, who faces separate allegations of rape and sexual harassment, may now be exposed to even more legal problems. Robert McClelland, Australia's attorney general, said his lawyers are looking into whether the leaks break any Australian laws.
