The U.S. has shared intelligence including maps with European allies that shows a buildup of Russian troops and artillery to prepare for a rapid, large-scale push into Ukraine from multiple locations if President Vladimir Putin decided to invade, according to people familiar with the conversations.
That intelligence has been conveyed to some NATO members over the past week to back up U.S. concerns about Putin’s possible intentions and an increasingly frantic diplomatic effort to deter him from any incursion, with European leaders engaging directly with the Russian president. The diplomacy is informed by an American assessment that Putin could be weighing an invasion early next year as his troops again mass near the border.
The information lays out a scenario where troops would cross into Ukraine from Crimea, the Russian border and via Belarus, with about 100 battalion tactical groups — potentially around 100,000 soldiers — deployed for what the people described as an operation in rough terrain and freezing conditions, covering extensive territory and prepared for a potentially prolonged occupation.
