Chairman of the United States Joint Chiefs of Staff Gen. Mark Milley told lawmakers that Kyiv may not withstand the first 72 hours of Russian invasion and that it could fall in less than 3 days, Fox News reported citing multiple sources with the United States Congress. Milley reportedly warned lawmakers in this week's closed-door briefings, adding that around 15,000 Ukrainian troops and 4,000 Russian troops could lose their lives if Moscow chooses to invade.
