President Joe Biden unleashed new sanctions against Russia and ordered the deployment of thousands of additional troops to NATO ally Germany.

He also acknowledged that the invasion — and efforts to thwart Putin — will have a cost for Americans. But he sought to reassure the public that the economic pain that may come with rising energy prices will be short-lived in the U.S.

Targeting Russia’s financial system, Biden said, the United States will block assets of Large Russian banks, impose export controls aimed at the nation’s high-tech needs and sanction its business oligarchs.

The president said the U.S. also will be deploying additional forces to Germany to bolster NATO after the invasion of Ukraine, which is not a member of the defense organization. Around 7,000 additional U.S. troops will be sent.
