The greatest intelligence failure in American history may not have been a foreign operation. It may have been America's inability to protect itself from its own president. For years, the evidence of Trump's extraordinary loyalty to Moscow has been mounting. His admiration for Putin, his attacks on NATO, his possession of highly classified American defence secrets, and his repeated willingness to advance Russian interests. Yet the most extraordinary part of this entire scandal is the American state itself. The FBI, the intelligence community, Congress and the entire national security apparatus have proved incapable of protecting the country from a president whose conduct has repeatedly raised profound questions about his loyalty. Russia spent decades trying to defeat the United States from the outside. Now Putin can watch an American president dismantle the Western order from within. And the institutions built to defend America have been unable to stop him. What an extraordinary national humiliation.
