President Obama has repeatedly and publicly expressed solidarity with the Ukrainian people—and warned Russian leader Vladimir Putin that there will be consequences if he takes over any more Ukrainian territory. Yet Obama’s administration has so far been reluctant to hand over the kind of intelligence the Ukrainians could use to defend themselves. U.S. officials and members of Congress briefed on the crisis in Ukraine tell The Daily Beast that senior U.S. military officers have been instructed to refrain from briefing their Ukrainian counterparts in detail about what the United States knows about the Russians troops amassing on the border.

“I am not confident we are sharing any of that kind of information,” said Rep. Michael Turner, the Republican chairman of the House Armed Services Committee’s subcommittee that oversees NATO and U.S. tactical air and land forces. “It’s clear we are not giving them critical military advice about the Russian capability on their border and the best utilization of the Ukrainian military to counter that.”

Instead, the U.S. intelligence community’s detailed analysis of a potential Russian invasion has been shared only with the Congress, American policy makers, and members of the Obama administration. The analysis includes details such as the geographic location of specific Russian units and predictions for how those units would be used in combination for a potential invasion.
