© Evan Vucci/AP President Biden gives a speech in Poland in March 2022, about a month after the Russian invasion of Ukraine. In past weeks, the White House has told Kyiv that it could soon see limits in support from the United States and other countries. We need speed — speed of our agreements, speed of our delivery … speed of decisions to limit Russian potential. The United States has about 10,000 personnel on rotation in Poland as part of the NATO alliance. The president’s last trip to Poland in March 2022 was full of symbolism and strong statements — both visually and verbally.
