The Biden administration is weighing sending military advisers and new equipment including weaponry to Ukraine as Russia
builds up forces near the border and US officials
prepare allies for the possibility of another Russian invasion, multiple sources familiar with the deliberations tell CNN.
The discussions about the proposed lethal aid package are happening as Ukraine has begun to
warn publicly that an invasion could happen as soon as January. The package could include new Javelin anti-tank and anti-armor missiles as well as mortars, the sources said.
Air defense systems, such as stinger missiles, are also under consideration, and the Defense Department has been pressing for some equipment that would have gone to Afghanistan -- like Mi-17 helicopters -- to instead be sent to Ukraine. The Mi-17 is a Russian helicopter that the US originally purchased to give to the Afghans. The Pentagon is now weighing what to do with them after the US withdrawal from Afghanistan in August.
