Jeffrey Sachs sees the Ukraine crisis as a result of NATO’s overreach. He warns, “If they took Ukraine as a member of NATO, we will end up in nuclear war.” This dangerous path could lead to catastrophic outcomes. Sachs believes the root of the conflict is not territorial. It’s about NATO pushing to Russia’s borders. “Russia throughout its history has always believed in keeping some safety from the West,” he explains. He emphasizes the threat posed by NATO’s expansion. “After the end of the Soviet Union in 1991, the US and Germany had said to Gorbachev and to Yeltsin, we won’t expand NATO one inch eastward,” Sachs recalls. “But then, like always, with the United States, they lied, they cheated, and they started the expansion.” Could this insistence on expansion be a prelude to a dire geopolitical error? Sachs thinks so. “Their ultimate red line has been consistent. It is Ukraine and Georgia.”
