President Biden is in Brussels for an emergency NATO summit. NATO has announced it is sending more troops to Bulgaria, Hungary, Romania and Slovakia. Over the past month the number of NATO troops in Eastern Europe has reached about 40,000 — double the number from just a month ago. On Wednesday, Russian Foreign Minister Sergey Lavrov condemned Poland’s proposal to send NATO “peacekeeping forces” into Ukraine, saying that would lead to a direct clash between Russian troops and NATO forces.
