“Russia's military aggression against Ukraine appears to have decreased sharply after the US on Dec 22 announced it would deliver arms to Ukraine. It seems to have worked,” Anders Aslund tweeted Tuesday.
However, some researchers show no support for Washington’s decision to provide lethal aid to Ukraine.
According to The Hill, Stephen Cohen, a professor emeritus of Russian studies at New York University and Princeton University, says the Trump administration’s decision to supply lethal weapons to Ukraine was a “mistake.”

Cohen, who has in the past voiced skepticism of allegations of collusion between the Trump campaign and Russia, also criticized the breadth of ongoing investigations into Moscow's role in the 2016 presidential election.
At the same time, according to RFE/RL, U.S. Defense Secretary Jim Mattis in his first remarks since the U.S. State Department announced approval of "enhanced defensive capabilities" for Ukraine said: "As long as no one wants to invade Ukraine, hopefully it won't have any big impact. They're defensive weapons."
