A huge leak of Pentagon documents uncovered over the past week has revealed how deeply the United States has penetrated Russia and other rivals. But it is also a reminder that the United States spies on its allies as a matter of routine - a practice that has risks for both Washington and friends alike.
There is no shortage of unflattering revelations. The documents paint a pessimistic picture of Ukraine's upcoming spring counteroffensive and point to potential problems in air defense and artillery. One report suggests that South Korea balked at supplying weapons to Ukraine. A separate document claims Egypt secretly planned to supply rockets to Russia, while another says NATO ally Turkey was approached by Russia's notorious Wagner Group, a private military contractor, to help procure supplies.
