Intelligence Sharing By The Us And Its Allies Has Saved Lives. Trump Could Test Those Ties

As Russia moved closer to invading Ukraine nearly three years ago, the United States and its allies took the extraordinary step of declassifying and sharing intelligence to expose Moscow's plans.

Information flew across the Atlantic from U.S. spy agencies to NATO and Western partners showing that Russia was poised to launch the biggest attack on a European country since World War II.

It was designed to muster support for Kyiv, and on the strength of the U.S. warning, some nations sent weapons to Ukraine , which moved some equipment out of the range of Russian strikes.

Now, officials are bracing for a potentially changed security landscape under President Donald Trump . He has criticized America's allies and lambasted its intelligence agencies . He's been accused of disregarding secrecy rules and hoarding classified documents .

Tulsi Gabbard, Trump's pick for director of national intelligence, has parroted Russian propaganda while his nominee to lead the FBI, Kash Patel, has promised changes that could significantly curtail the flow of intelligence to America's friends. Both are expected to face sharp questioning from lawmakers during confirmation hearings Thursday .
