Russia Is Massing Troops on the Ukrainian and Polish Borders and the US Is Unsure What This Means

Admit nothing, deny everything, blame NATO and the West. That seems to be the Russian playbook under Vladimir Putin. The Russians have been massing troops on the Ukrainian border since spring. Many troops still remain in the region. Now, Russia is reinforcing them covertly as many experts believe that Moscow may be planning on making another move into Ukraine.
Russia and Belarus are also conducting large-scale exercises on the border with Poland as Moscow continues to act increasingly more aggressively in the region.
