"And if Russia attacks the United States or our Allies through asymmetric means, like disruptive cyberattacks against our companies or critical infrastructure, we are prepared to respond."

"If Russia does invade in the days and weeks ahead, the human cost for Ukraine will be immense. And the strategic cost for Russia will also be immense."

"If Russia targets Americans in Ukraine, we will respond forcefully."

"If Russia commits this breach by invading Ukraine, responsible nations around the world will not hesitate to respond."
