...Both the danger of stoking tensions with Moscow and becoming too close to a regime in Kiev that exhibits disturbing features should caution the Trump administration against boosting military aid to Ukraine. It is an unwise policy on strategic as well as moral grounds. Trump administration officials should refuse to be intimidated or stampeded into forging a risky and unsavory alliance with Kiev out of fear of being portrayed as excessively “soft” toward Russia. Instead, the president and his advisers need to spurn efforts to increase U.S. support for Ukraine. A good place to start would be to restore the Obama administration’s refusal to approve arms sales to Kiev. Washington must not pour gasoline on a geo-strategic fire that could lead to a full-blown crisis between the United States and Russia.
