KYIV, May 2 - Ukraine is holding close the details of its spring counteroffensive to prevent the leak of sensitive information that could compromise its positions on the battlefield, POLITICO reported citing two European officials who are in touch with military leaders in Ukraine.

The officials said their Ukrainian counterparts have cited the alleged leak of the classified documents from Massachusetts Air Guardsman Jack Teixeira as one of the reasons Kyiv is holding back from sharing counteroffensive information, including its timing, where and how many troops they plan to move into position for the operation.

The spilled documents included detailed information about the war in Ukraine, such as the position of Kyiv’s troops, its weapons stockpiles and casualty estimates. In the days following the leak, U.S. officials scrambled to assure Ukraine and other allies in Europe that it was putting protections in place to prevent a similar breach from happening in the future.

But officials in Kyiv are still on high alert. While Ukraine is still likely sharing some basic intelligence with the U.S. and other European countries that have supported it with weapons over the past year, officials inside the country are working to prevent the widespread dissemination of details related to battlefield planning, the European officials said.

A Ukrainian lawmaker, who like others spoke on the condition of anonymity to discuss sensitive deliberations, said that top officials in Kyiv also had withheld details about the counteroffensive from other politicians inside the capital.

“There are only a few people in the country that know the plan,” the lawmaker said.

A U.S. defense official said there hasn’t been any change and that Washington and Kyiv still have the same level of information-sharing. There have been no signs of Ukraine keeping anything from the U.S., the official continued.

National Security Council spokesperson John Kirby, asked by NatSec Daily if the administration feared being kept in the dark by the Ukrainians, said silence ahead of the launch wouldn’t be a surprise. “They don’t have an obligation to notify us or tell us in advance,” he told reporters Monday, adding “oftentimes we certainly do have a sense because we’re in daily communication with them.”

The U.S. still supports Ukrainian operations with real-time information and intelligence, Kirby continued. “What we’re focused on is not whether we get some sort of heads up. We’re focused on making sure that they have everything they need for when they’re ready to go.

Other Biden administration officials insist that Ukraine has never been fully open with the United States about its military plans. While Washington and Kyiv are in close touch, they naturally don’t share everything, and so there was never an expectation that Ukraine would call up the White House and say the counteroffensive begins on X day at Y time.

“They’ve been stingy with information from the beginning,” a U.S. official said. (po/ez)
