Putin thought that he could easily topple Kyiv's democratically elected government. He thought that the wider world would let him get away with it. He thought that our unity would splinter, but he was wrong - on each and every count.

All of this is huge progress.

As Secretary of Defense, I will also not hesitate to take any additional measures necessary to safeguard our nation's secrets, accordingly, I am directing the Under Secretary of Defense for Intelligence and Security to conduct a review of our intelligence access, accountability and control procedures within the Department to inform our efforts to prevent this kind of incident from happening again.

As President Biden has made clear, we will take all necessary measures to defend our people and will always respond at a time and place of our choosing, no group will strike our troops with impunity.
